SDK - Generator - Mass Exceed on a single utxo set evaluation round should not exit if there are other utxos that could fit

[IzioDev]

Describe the bug
Under certain conditions (more below), the Generator could have picked a valid (according to KIP-9 rules) UTXO to spend according to the request conditions, but has failed while supposedly only attempting one of them.

Method: generator.next()

Input parameters:

• payload

To make it simpler, here are the UTXO:

console error: Storage mass exceeds maximum

Expected behavior
Generator should potentially fail on the utxo that has 0.29624618 TKAS but should eventually try another combination for the request, in this case the utxo that has 0.5 TKAS.

I volunteer to implement a fix, but I'd need guidance.

[aspect]

I am available on TG or Discord (TG is better, but ping me on Discord to connect via TG) and can guide you through the implementation details.

[IzioDev]

For the record, I'm in the process of investigation, aspect is helping me :)

Edit: due to recent business, i had to pause. Still on my list, but if someone wants to frontrun, please do so :)
