FIREFLY-1623: Improve python API for tables

[jaladh-singhal]

Fixes FIREFLY-1623

• Added url param to show_table() that can be used instead of file_on_server or target_search_info - this is similar to show_fits() which accepts url param as part of additonal params
• Documented usage of url param for both table and image
• Created two methods for sorting/filtering a loaded table, with documentation

Bonus: removed internal classes from API reference because they are of no use to end-user and were causing confusion

Note: I wanted to create a 3rd method to set UI options too but it's more complicated so I deferred it to FIREFLY-1631 in the interest of time

Testing

Copy the method examples (added in rst docs) in your notebook with firefly_client installed, they should work

The changes look good to me. I tried them in a notebook. I left a couple of suggestions inline.

Do the changes warrant a bumping of the minor version?

In the course of testing, I found that table overlays did not work at all in Safari 17.6, but they worked as expected in Chrome.

@stargaser yes, we will make a new minor release soon for the workshop
