feat(wallet): Add Gap Limit Options

[coreyphillips]

Description

• Upgrades Beignet to 0.0.23.
• Implements gapLimitOptions from upgrade.
  • New wallets default to a lookBehind of 5 and a lookAhead of 1 to limit queries to Electrum.
  • Restored wallets temporarily use a lookBehind of 20 and a lookAhead of 20 during the initial scan. Once this scan finishes it reverts back to the default lookBehind-lookAhead of 5-1.
  • If you think the 5-1 defaults are low, we can try something higher like 5-5, but restored wallets may come close to the limits of what a given Electrum server will tolerate for extremely active users or heavy testing sessions.
• Adds two dev-only views.
  • Monitored Address Types: Found in "Settings->Advanced->Bitcoin Address Type" beneath "Monitored Address Types" allowing us to adjust what address types are actively being monitored. An app restart is required for changes to take effect.
  • Gap Limit: Found in "Settings->Advanced->Gap Limit" allowing us to adjust the gap limit in Bitkit as needed for testing/debugging.
• Updates broadcastTransaction, getReceiveAddress & getBalance methods.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)

Tests

• No test

QA Notes

• Restores should continue to work as expected. Once a restore is successful and the initial scan is complete we should be able to observe that the gap limit lookAhead and lookBehind were reverted to their default of 5-1 in "Settings->Advanced->Gap Limit".

How does lookBehind: 20 works during wallet restore, it still can't go behind index 0, right?

A lookBehind of 20 is not necessarily needed during the initial scan for a restore since we're scanning all addresses as we generate them anyway, it's just there to conform to the standard/default.
