New BSIP: voting with non-core asset, and asset-specific committee

Currently only CORE can vote for certain things E.G. witnesses, workers and the committee.

It's been demanded by the community for a long time that, holders of other assets can vote with their assets, for things related to those assets.

Another thing is asset-specific committee. Currently it's able to set committee of an asset to top-N holders. I think it would be useful if the committee can be decided by voting.

Update:
Example of asset-specific committee with top-N holders: https://cryptofresh.com/u/stealth-mgmt

No implementation files, tests, or entry points are named. Start by reviewing the BSIP proposal process and the linked Cryptofresh example, then define the voting and asset-specific committee rules precisely; done means a complete proposal that resolves the requested behavior and can be evaluated for protocol adoption.
