…response types. Adding missing getBlockDetailsByHash() method. Added real ots_ raw data to the unit tests to make them more accurate. Added the "reasoning" from the otterscan docs to the JSDoc comments.

Adding a new subclass of JsonRpcProvider supporting erigon's ots_ (Otterscan) methods. The ots_ namespace provides some very helpful methods, most importantly being able to quickly fetch a list of all transactions belonging to a given address.
If your node supports the ots_ namespace, this provider will give you access to 11 new RPC methods: ots_getApiLevel, ots_hasCode, ots_getInternalOperations, ots_getTransactionError, ots_traceTransaction, ots_getBlockDetails, ots_getBlockTransactions, ots_searchTransactionsBefore/After, ots_getTransactionBySenderAndNonce, ots_getContractCreator
