numba now is a mandatory requirement

[kakulukia]

also added python 3.11 to the test matrix
indicator files have been rearranged with isort as i touched a lot of them

Also added a PR here: jesse-ai/docs#63

great pr!
something that can be added, i've notice there is an overhead for start a simulation with numba vs without numba.
we can cache the compilation time to avoid this overhead!
maybe this can be a good idea to add it too!

I certainly can add this cached=True
Do you also have a good idea of how to measure the performance gain? I will have as look at the test performance with our without cache.

Ill do 1 or 2 example,
What im going to do is run a simulation of daily timeframe for 1 day. Where the only thing this strategy do is to import several indicators, the imports will do the compilation.

By making the simulation the shortest that possible, the strategy doesnt really needs to do anything.

As i said ill do a comparision myself.
Cheers.

This is indeed a great pull request. Thank you for being careful with Python 3.8 version.
