Allow partial offer matches on Pool Lite

[Bitcoinite]

Is your feature request related to a problem? Please describe. When trying to submit a public ask offer to LOOPs bid, I receive an insufficient account balance error (see screenshot attached). My account balance can't match the whole bid order listed, but it can definitely match LOOPs min channel size requirement from that bid offer.

Describe the solution you'd like Pool should create a ask offer that matches the selected bid offer with my max available account balance.
