Make CheckTendermintError to handle ErrTxInMap

[zbvs]

Summary

CheckTendermintError also needs to handle ErrTxInMap with correspond { Codespace, Code-Number }, as many GRPC clients want to check TxHash duplication or sequence number duplication error

Problem Definition

Currently, CheckTendermintError doesn't handle ErrTxInMap error ( https://github.com/line/lbm-sdk/blob/main/client/broadcast.go#L59 ),
which occurs when Tx is in mempool and not confirmed yet. ( https://github.com/line/ostracon/blob/main/mempool/clist_mempool.go#L302 ).

As many grpc clients want to check sequence number duplication with { Codespace, Code-Number }, it needs to handle ErrTxInMap for GRPC clients, so that it can return { Codespace, Code-Number }

Proposal

Make CheckTendermintError to handle ErrTxInMap

We will discard duplicate Tx in the future. (ref)
