updated dbprocessing code for sqlalchemy 2.0

[ezd1000]

Updated a series of errors so that dbprocessing code works for both sqlalchemy 2.0 and sqlalchemy 1.4. Closes #135.

• Adding/Removing bind=self.engine

• Join syntax needs to be reorganized so that the order of the second argument aligns with the first argument, as well as deleting extra parenthesis

• Replaced Query.get() with Session.get()

This would close #135, so should edit the PR description to say that. (Last item in the PR checklist, see #120 for an example, also some information here.)
