Change MaxTxBytesSize/MaxTxDataBytesSize default values

[agnusmor]

Rationale

The MaxTxBytesSize and MaxTxDataBytesSize config parameters limits the size of the L2 Tx. The current default values 30132 and 30000 are causing some issues in mainnet/public environments, as some dapps needs to send L2 tx greaters than these values.

Implementation

We need to increase the value of this parameters in all the toml config files and also for the default value (default.go). The maximum size set in the SC for a L1 tx is 120000, therefore we can set the default values for MaxTxBytesSize to 100132 and MaxTxDataBytesSize to 100000. This values left some margin to the max value accepted by the SC
