Split deps

[Giulero]

I want to update the installation procedure for pruning dependencies that the user might not need in this PR.
For example, the installation would require PyTorch even if the user just needs the CasAdi interface.

Now the installation would need:

• jax interface:

  pip install .[jax]

• casadi interface:

  pip install .[casadi]

• pytorch interface:

  pip install .[pytorch]

or, if the user does not want to clone the repo:

pip install adam[selected-interface]@git+https://github.com/ami-iit/ADAM

I took also the occasion to change the import syntax.
Before:

from adam.casadi.computations import KinDynComputations

After:

from adam.casadi import KinDynComputations

The import syntax used before is still working, so the old code using adam does not need to be updated.

It is a bit confusing to have the sentence mentioning conda in a section that is not related to conda, but rather to the use of pip + apt .

Thanks! A bad copy-paste :/

Given that the version that is currently in master (i.e. after #20) has been the default one installed if somebody cloned the repo in the last two months, could it make sense to tag it as 0.0.2 and then merge this PR?

Sure! I'll update also 5c54e46.

Thanks @traversaro! Merging.
