BUG/FEATURE alr install does not allow uninstalling crates

[Irvise]

As the title says (and is indicated in the documentation) alr install does not have a way of uninstalling crates... I found about this while answering a question about uninstalling crates in the forum. Reproducing what I wrote there:

"""
I took a look at the docs and Alire does support uninstalling toolchains… But looking a bit deeper, in the alr install section it says:

At present, only binary releases can be installed (e.g., compilers, gprbuild, gnatprove). There is no ability to uninstall releases either (but reinstallation can be forced).

So… I am even surprised myself, but it does not seem to support uninstalling crates via alr install… I will se if this has already been reported in the Alire repository and if not, make an issue.

Best,
Fer
