[ENH] Add TsGroup.merge_group method

[qian-chu]

Implements https://github.com/pynapple-org/pynapple/issues/251.

Added a static method TsGroup.merge_group() as well as a tsgroup.merge(). Documentation with examples is included as well.

[qian-chu]

Hi Qian-Chu. Thanks for your contribution, this is great. Very neat docstrings, and well thought out method. I would ask you a couple of edits before we can merge this:

1. Run linters and formatters

black pynapple/core/ts_group.py
isort --check pynapple --profile black
flake8 pynapple --max-complexity 10    

2. Add tests of your method hitting all the exceptions. you can use @pytest.mark.parametrize to loop over multiple tsgroup and kwargs configs.

Cheers, Edoardo

Will do! Thanks for reviewing and providing feedback!

I re-based this into the dev branch, but up to @gviejo.

@qian-chu this is definitely going to be in main but we usually have merge first into dev, so that we have some time to try out the new feature.

Many thanks @BalzaniEdoardo for all the suggestions. I just moved the examples from merge_group() to merge(). Feel free to take a look. Not sure how to implement See Also merge_group() as a link but I did leave a mentioning there :)

I have no problem with dev vs main! Take your time.
