[Feature]: Add a post_init method to get_class

[h-mayorquin]

What would you like to see added to HDMF?

Extensions creates can build an API for their work using the following:

AClass = get_class("ObjectOnTheSpec", "ndx-extension")

It would be nice to have a mechanism to do checks with their arugments when using the get_class convenience method.

What solution would you like?

Something that looks like this:

def post_init(**init_kwargs):
    
    # Do the check here

ACheckedClass = get_class("ObjectOnTheSpec", "ndx-extension", post_init=post_init)

Do you have any interest in helping implement the feature?

No.

Following the syntax for post_init in Python dataclasses, let's use this call signature def post_init(self)
