local tx submission

[teebaumcrypto]

Situation:
I try to send multiple tx's via local tx submission to my node.

Result:
If a tx is rejected by the node the local tx submission is stuck in the state of agency is theirs.
all subsequent tx's fail.

The channelbuffer temp vector is not cleared.

I also had the error that the tokio broadcast channel lagged, so I increased buffer in the plexer impl to 2000.
