Upgrade oscrypto to 1.2.1

[noah-vetcove]

As a part of an upgrade to Mac OSX Big Sur, oscrypto 1.2.0 no longer works. This is fixed with version 1.2.1 https://github.com/wbond/oscrypto/pull/47

While attempting to upgrade our python to version 3.9.1 (including the new package version enforcer), pyas2lib was the problem child with oscrypto pinned to version 1.2.0.

This PR should be updating the oscrypto dependency to 1.2.1.

I ran tests and everything passes:

@abhishek-ram if you could take a look at this, that would be awesome!

[noah-vetcove]

@abhishek-ram is there anything else you need me to do to get this published in a new version?

[abhishek-ram]

Nothing from you, I will push a release this week
