`round_num` and `block` no longer allowed when querying balances

[BunsanMuchi]

Subject of the issue

Your environment

py-algorand-sdk 2.0.0

Steps to reproduce

1. Call the method asset_balances(asset_id, round_num=number) or asset_balances(asset_id, block=number)

Expected behaviour

A balance return at the given block/round number according to the docs: https://py-algorand-sdk.readthedocs.io/en/latest/algosdk/v2client/indexer.html

Actual behaviour

It seems like the method got changed, and doesn't allow for this parameter anymore, I believe it's a case of outdated docs or an undocumented change, since I get the following TypeErrors:

TypeError: IndexerClient.indexer_request() got an unexpected keyword argument 'round_num'
TypeError: IndexerClient.indexer_request() got an unexpected keyword argument 'block'

Thanks for identifying this issue. It appears that the docs getting generated are inaccurate and do not conform with the actual v2 API which does not accept block/round number.

This discrepancy ought to be fixed as soon as possible, even though it probably is a longstanding issue.

Yep, I've noticed it happens with a lot of places on both the SDK and the docs of the SDK. Plus the few methods that still support round_num or block end up with either rewind issues or just printing the current round, leading to confusing results. Thanks!

If you know off hand other instances, we welcome your feedback.

The fix didn't make it into today's release, but will go in the next one.
