feat(api):better TransactionState.TransactionState->TransactionState.…

[arc0035]

I'm developing java sdk, when I try to generate java classes due to proto, it would generate illegal java code.

This is because tx_types.proto defines TransactionState alongwith enum TransactionState:

message TransactionState {
TransactionId id = 1;
enum TransactionState {
TRANSACTION_STATE_UNSPECIFIED = 0; // default state
TRANSACTION_STATE_REJECTED = 1; // rejected from mempool due to, e.g., invalid syntax
TRANSACTION_STATE_INSUFFICIENT_FUNDS = 2; // rejected from mempool by funds check
TRANSACTION_STATE_CONFLICTING = 3; // rejected from mempool due to conflicting counter
TRANSACTION_STATE_MEMPOOL = 4; // in mempool but not on the mesh yet
TRANSACTION_STATE_MESH = 5; // submitted to the mesh
TRANSACTION_STATE_PROCESSED = 6; // processed by STF; check Receipt for success or failure
}
TransactionState state = 2;
}
It would generate this form of java code which is illegal in Java:

A fast way to optimize this is to change the name of the enum: TransactionState.TransactionState->TransactionState.TramsactionStateEnum
