Support more encoding/decoding types

[There are several encoding + decoding types that are not yet working](https://github.com/dawsbot/essential-eth/blob/6705a3bd13e3a1ccaacbc91f12c0b07a643d9499/src/classes/utils/encode-decode-transaction.ts#L132).

Enabling signing will be dangerous until most or all encoding/decoding types are working with `essential-eth`.

To start, we should find production smart-contracts which have unique and difficult types then add support via jest tests like was done with [the CRV smart-contract tests](https://github.com/dawsbot/essential-eth/issues/130). [The readme outlines types that are already covered properly](https://github.com/dawsbot/essential-eth#contract). Assume all others will error and this issue is to track adding support.

Start in src/classes/utils/encode-decode-transaction.ts around line 132, then review the README’s list of covered contract types. Use the CRV smart-contract tests linked from issue #130 as the testing reference, and identify production contracts with unsupported types. Done means the selected additional encoding and decoding types work under Jest tests.
