Address Switching - Generating and using new Address in Light Wallet

What would you like to be added:

Currently, on the Light Wallet, only index:0 addresses are used. The internal implementation of jellyfish-wallet allows multi addresses to be used. This issue calls for implementing wallet management with multi addresses supported.

1. Listing all the active addresses within the wallet.
2. Generating a new Address n+1 and storing the max index to know how many addresses have been generated.
3. Discovering all addresses on the wallet via https://github.com/DeFiCh/jellyfish/blob/47c3dabe7995bbfe8e7812ea1dfd1e885a6355f7/packages/jellyfish-wallet/src/wallet.ts#L69-L77 and storing the max indexes.

Assumptions:

• We are not using Node-like address management where all addresses are pooled together with one balance, for simplicity reasons each address is an account within the wallet system that the user can switch to.
• We are following a Metamask like experience
• We are not going to store all addresses like a wallet.dat file, we just need to track where the max index is.

Max Index Length determines the maximum number of activated addresses allowed in the wallet. Accounts are considered active if the address contains any transaction activity. You can always generate an address (+1). You can’t generate another address until you have activated the previous address. You active a previous address by using it. (contains any transaction activity)

• Max Index Length = 1, only 1 default address
• Max Index Length = 2, 2 addresses [Active, Active/In-Inactive]
• Max Index Length = 3, 3 addresses [Active, Active, Active/In-Inactive]

• Avatars of wallet are already implemented.

Acceptance Criteria: User generates new address and perform transactions from new address Android:

• Balances > current address present > make a transaction > check whether able to add a new address
• Balances > current address present > do not make any transaction > check whether unable to add a new address
• Balances > current address present > make a transaction > Check whether able to add a new address > make a transaction from new address > Check whether able to add a new address
• Balances > Refresh > Select Address > Selected address should retain
• Logout > Login > Restore Wallet > All the addresses which were added should get restored
• Balances > Select an Address > Current active should have active tab on display
• Balances > Receive > Current Active address should be displayed
• Create a new wallet > Check whether any addresses from old wallet is not displayed

iOS:

• Balances > current address present > make a transaction > check whether able to add a new address
• Balances > current address present > do not make any transaction > check whether unable to add a new address
• Balances > current address present > make a transaction > Check whether able to add a new address > make a transaction from new address > Check whether able to add a new address
• Balances > Refresh > Select Address > Selected address should retain
• Logout > Login > Restore Wallet > All the addresses which were added should get restored
• Balances > Select an Address > Current active should have active tab on display
• Balances > Receive > Current Active address should be displayed
• Create a new wallet > Check whether any addresses from old wallet is not displayed
