Shuffle tiers need to account for minimum change output being >= 546 sats (dust threshold)

I was getting errors during shuffling because some participant was producing change outputs <546 sats.

The rule is now:

minimum_input_size = tier_amount + fee_per_player

It should become:

minimum_input_size = tier_amount + fee_per_player + min_change_dust

The other alternative is to just give the dust change to the miner as extra fee. Investigating that now and it looks pretty possible.

Fixed it. I went with the "dust outputs go to miner fee" route..
