Fix mac silicon for napari

[paddyroddy]

I've been struggling to develop the whole time and realised stuff is on conda now which wasn't before, so have worked it out and written it down. h5py seems to now be universal on PyPI, so no longer needed in the environment.yaml.

Related #217. Still think it would better to remove the environment.yaml file in favour of documenting the fact that you just need to install those packages from PyPI. For example, for this to work I've had to add pyqt to environment.yaml, whereas in pyproject.toml we are making pyqt only required when doing pip install btrack[napari].

I think it's fine to remove environment.yml now. I never use it nowadays anyway, and these new instructions in the README are clear

[paddyroddy]

Have decided to remove the environment.yml and improve the docs etc for installation.

Fixes #217.

[paddyroddy]

Fixes #218.
