Selector for custom deposit lot size

[danimesq]

Should be shipped before the r1, for better testing.

Suggested sizes:

• [ ] 0.01 (current)
• [ ] 0.02
• [ ] 0.05
• [ ] 0.1
• [ ] 0.2
• [ ] 0.5
• [ ] 1
• [ ] 2

Doesn't matter if the mainnet launch will not support all bigger lot sizes, it will be good for full test coverage for when it is implemented.

Thanks for this @DaniellMesquita! Lot sizes are actually governed by the protocol - you can see the initial sizes here and the governance here.

Closing this in favor of #255, which will go out in the next release.
