feat: support liquidity quotes

[andrew-g-za]

Hey chaps,

At last, the liquidity quote codec. I've also fixed a few things here and there, particularly our .toString convention of starting with 'Impl{..}' - which Impl?

p.s. I had some weird merging issues, hopefully it doesnt get too confusing. If it does, i'll just check out the dev branch and drop my changes on top (since we squash + merge, it should be the same i think)
