Add AMM support

[nkramer44]

Do not merge this until the AMM amendment is endorsed on XRPL Mainnet

This PR adds support for XLS-30 AMMs.

New Transaction Types

• AmmCreate
• AmmDeposit
• AmmBid
• AmmVote
• AmmWithdraw
• AmmDelete

New Client Methods

• XrplClient.ammInfo calls amm_info, taking AmmInfoRequestParams as a parameter and returning an AmmInfoResult

Other Changes

• XLS-30 introduces a new serializable type called Issue (used to specify Asset and Asset2 in an AMM). This PR adds an Issue type (called IssueType) to the binary codec module to encode/decode these values.
• This PR includes both objects for the AMM ledger entry as well as the amm_info result object. While AmmInfoResult.amm() is very similar to the AMM ledger entry, the rippled API formats the AMM object differently in responses to amm_info. The AmmObject in this PR is basically inaccessible because XrplClient doesn't support the ledger_entry RPC, but it will be good to have in the codebase once we add that method
