Decode bytes to strings in Python Object API

[sethraymond]

Type-hints for the Python Object API are incorrect for strings - the _UnPack() method does not convert bytes to strings. This PR introduces an optional flag (false by default) that enables decoding the bytes into string objects.

Resolves #5997

@aardappel bump, can we get the CI run on this PR?

[aardappel]

You can get the CI to run by rebasing, it is out of date.. I guess I'll do that for you.

Is this meant to be self.name = nestedUnionTest.name.decode('utf-8') ?

[sethraymond]

nestedUnionTest is not an object API type, so the only way to access the name from that object is via nestedUnionTest.Name().

This change is intentional, but if you're asking for a modification to the auto-generated code, I could change the autogeneration here to be

code += GetIndents(3) + "self." + field_field + " = " + struct_var + "." + field_method + "().decode('utf-8')";

Then this would read

self.name = nestedUnionTest.Name()
if self.name is not None:
    self.name = nestedUnionTest.Name().decode('utf-8')

It's functionally the same, though, since self.name is set to nestedUnionTest.name() a couple lines beforehand. I personally think the current implementation is a bit more readable, but I'm open to suggestions.

Looks ok, I guess? @dbaileychess
