Add more gates to pennylane_to_tk conversion

[CalMacCQ]

Current the pennylane_to_tk function only works on a subset of the available pennylane gates.

Ideally it should work on a wider range of pennylane gates. At least those for which there is an exact replacement in pytket.

The supported pennylane gates can be found here -> https://docs.pennylane.ai/en/stable/introduction/operations.html
and the supported pytket OpTypes here -> https://cqcl.github.io/tket/pytket/api/optype.html

Once these extra gates are added there should also be tests added to pytket-pennylane/tests/test_conversion.py
