Replace FilePointer with universal pathlib

[delucchi-cmu]

Change Description

Related to #320, #313, #307
Closes #79

Solution Description

Use fsspec's project, universal-pathlib as a path provider. In this way, everywhere we currently pass in a FilePointer we can use a Path instead, and when we need to create remote connections, use UPath.

I haven't looked in details, but it looks great. I have an only question, should we allow something like str | Path | UPath for "very public" interfaces like read_from_hipscat?
