There was a regression on the i*i=-1 test from the work on constants.
Add it back and extend it to any case that produces real-only results
when auto-simplify is on.

Add `R→D` and `D→R` as purely numerical functions, compatible with HP-48.

- Convert a number to the target unit using current angle mode
- Convert an angle to the target angle unit

When the `SetAngleUnits` setting is enabled, `asin`, `acos` and `atan`
will return values with an angle unit that corresponds to the current
angle mode.
The evaluation of such values should be independent from the current
angle mode.

This release does not contain much because FOSDEM took a lot of energy.
New features:
* menu: Connect `ceil` and `floor` functions
* Add real to polar conversions
* units: Add `dms` unit to angles menu
Bug fixes:
* decimal: Compute `ln(0.002)` correctly
* integer: Do not parse degree sign if in a complex
* units: Fix parsing of angle units
* font: Add radian glyph

Add the `dms` unit to angles menu, with value "one degree" so that we

This release focuses on heavy testing of the new variable-precision
decimal stack. Adding tests also means finding bugs.
Another significant change is support for fixed-precision
hardware-accelerated floating point, using 32-bit and 64-bit IEEE754
binary floating-point representation. Since this uses a binary format,
some decimal values do not map to decimal correctly. For example,
displaying 1.2 with a large number of decimals will show residue,
because 1.2 does not have an exact (zero-terminated) representation in
binary.
New features:
* plotting: Make refresh rate configurable
* menu: Add `/` key to `FractionsMenu`
* hwfp: Add support for hardware-accelerated floating-point
* menus: Add hardware floating-point flag to `MathModesMenu`
* ui: Allow multiple uses of `.` to insert DMS separators
* HMS: Editing of HMS values in HMS format
Bug fixes:
* stats: Fix crash on `variance` with single-column statistics
* algebraic: Clear error before evaluating the function
* functions: Correctly emit a type error for non-algebraics
* ui: Make sure we save stack if closing the editor
* logical: Fix mask for rotate left with 64-bit size
* logical: Make sure we save args for single-argument logicals
* flags: Update flags on `FlipFlag`, consume them from `BinaryToFlags`
* stack: Show multi-line objects correctly
* lists: Returns `Bad argument value` for index with bad arguments
* lists: Return an empty list for tail of empty list
* arithmetic: `→Frac` should not error on integers
* power: Do not shut down during `WAIT` if on USB power
Improvements:
* menu: Shorten the labels `→QIter` and `→QPrec` to avoid scrolling
* stack: Avoid running same code twice on simulator
* ids: Add aliases for hardware floating point
* functions: Optimize abs and neg
* ui: Replace calls to `rt.insert` with calls to `insert`
* menu: Reorganize fractions menu
* dms: Do the DMS conversion using fractions
* list: Adjust multi-line rendering
* copyright: Update copyright to 2024
* text: Return null text when indexing past end of text
Testing:
* tests: Increase the delay for help to draw
* tests: Add tests for hardware-accelerated floating-point
* tests: Add shifts and rotate tests
* tests: Check flag functions
* tests: Test DMS and HMS operations
* tests: Add test for `integrate` using decimal values
* tests: Test multi-line stack display
* tests: Add tests for `GETI`
* tests: Min and max commands
* tests: Repair last regression test
* tests: Check behaviour of 0^0
* tests: Avoid string overflow in case of very long message

When running the tests under load, we frequently have issues with the

When we have a very long message, we were moving `pad` beyond the end
of the padding string. This actually happens for a few rare parsing
tests where the command name is very long, so the overflow check is
necessary.

The `FlipFlag` command was not writing the flag state, in effect doing
nothing. Setting the `write` variable ensures that the state is
updated.

In order to correctly move the selection, it's important to call
`insert`, which knows how to update it, instead of `rt.insert`, which
does not. This also removes a number of explicit `cursor` updates.

Hitting `.` on an existing decimal separator inserts `°`.
Hitting `.` again reverts to `.`.
Hitting `.` after entering a decimal part inserts `′`, and the next
one inserts `″`. This will replace `.` with `°` if necessary.
