refactor!: Rename tk2 encoder names to tket

[aborgna-q]

No functionality changes, only renames that we didn't do in #987

I'm not touching the decoder code, since it's already being modified by #1030

BREAKING CHANGE: Renamed various pytket encoder-related structs and methods from tk1* to pytket

chore: Rename tk2 encoder names to tket (#1037)

Looks like there are some merge conflicts.

Forgot to change the base back to main

Happy with renaming "tk2" things to "tket". Not so sure about renaming "tk1" things to "pytket" and "legacy".

• It's not clear why it's sometimes one and sometimes the other.
• It leads to some funny names, like PyPytketEncodeError.
• It emphasizes a difference of language, which is not really the point.
• Maybe it is a bit early to be calling old-tket "legacy".

Would it be so bad to keep using "tk1" as code for old-tket?

[aborgna-q]

Fair enough. I removed most changes, but left the main ones I wanted;

• Tk1EncoderConfig -> PytketEncoderConfig. The serialization submodule is called this pytket, and we do this already with the decoder refactor.
• Tk1ConvertError -> PytketEncodeError. We are adding a separate decoding error, so it's a good time to change this
• Tk1EncoderConfig -> PytketEncoderConfig. Same thing, the decoder is not only for tk1 operations
• Rolled back the "legacy" names, but kept Tk2Emitter -> TketOpEmitter, since the operations are now called that.
