Updated ListAssetRequest to include additional filter options

[itsrachelfish]

Resolves #876

This PR adds new filter options to the ListAssets RPC call.

• The ListAssetRequest proto definition was updated to include the new filter options.
• The fetchRpcAssets function was refactored to accept a AssetQueryFilters argument so that separate arguments don't need to be added for each filter option.
• The assets store constraintsToDbFilter function was updated to use the new filter options.
• And the assets.sql file was updated to include a new maxAmount option.

looking good!
it's in the right direction 💯

@GeorgeTsagk @guggero I updated the code to filter assets based on the tweaked script key instead of the internal script key ID. I ran into some weird issues with the automated tests, for some reason I was unable to filter the 10th asset:

assetGen:    assetGen.assetGens[9],
anchorPoint: assetGen.anchorPoints[4],
amt:         777,
scriptKey:   scriptKeyWithScript,

Oli said this might have something to do with an underlying issue with the specific anchor point or asset generation, but I'm not sure why this particular asset is "cursed" 😅

I worked around the issue by adding a script key to the 3rd asset and was able to filter it as expected.

super close 💯
mostly styling related comments

should also add the filter options to the cmd command but since they weren't there in the first place this can be done in a different PR

[guggero]

Almost there.
