Python 3.14 support

[MatthieuDartiailh]

Some backward incompatible changes are also introduce regarding:

• BINARY_OP that now requires a BinaryOp object as argument (for Instr)
• FORMAT_VALUE that now requires a FormatValue object as argument
  This align the behavior of those instructions with others using an enum and hence requiring one.

3.14 tests are passing locally with 3.14.0b3 without coverage measurement

[makslevental]

Hey just curious is this ready to land? Anything I can do to help it along?

[MatthieuDartiailh]

Some test regarding FORMAT_VALUE and BUILD_INTERPOLATION are missing. The changelog need to be updated too and I did not review the docs. If you want to help with the tests you are welcome.

[makslevental]

Will do - will send soon :)

[MatthieuDartiailh]

Actually tests are also missing for validation of the argument of the following instructions: BINARY_OP, FORMAT_VALUE, SPECIAL_METHOD, COMMON_CONSTANT, LOAD_SMALL_INT
For this you can extend: test_instr.py::InstrTest.test_invalid_arg

[makslevental]

FYI you did/do already have a test for arg validation for FORMAT_VALUE :)

[makslevental]

Add some more tests anyway #167
