Candy Machine Feature flags proposal

[stegaBOB]

Uses the UUID as feature flags. Checks byte offsets to determine if a feature is active. Implemented working collections flag as POC.

I like this change. @austbot @bhgames there is no currently intended use for the UUID moving forward in CMv2, right?

[bhgames]

None whatsoever

As per our Discussion @stegaBOB lets move this feature to have a version in the UUID:
Do a bit of analysis to make sure our new version wont get tipped by an existing uuid: you will need a delimiter before the version byte to ward off any collision.

Then in the program use a version to determine what version of the config account to use.
You can get fancy with traits and make this nice and then all the candy machine configuration will be in the config account.

This can actually made the collection config pda irrelevant. In general great idea to put the uuid to good use.

@stegaBOB how is the new way going?
