Adding send raw tx - Githubissues

Hello, I'm currently working in a chain signatures library to create transaction payloads for multiple Blockchains (including Near itself).

As part of the omni library, I included a way to build a signed payload for Near transactions that can be propagated.

Source: https://github.com/EdsonAlcala/omni-transaction-rs/blob/master/src/near/near_transaction.rs#L37

In the image above, if you notice, the return type of build_with_signature is a Vec< u8 >. Then if I want to send it to a Near network using near-jsonrpc-client-rs, it won't be possible (or perhaps I'm missing something). But I saw that send_tx only accepts a SignedTransaction. However my transaction payload is already signed.

So I thought about adding a send_raw_tx, that only encodes to base 64 and send the payload to the network.

Notice the encode_signed_transaction function:

You can see how I used it here https://github.com/EdsonAlcala/omni-transaction-rs/blob/master/tests/near_integration_test.rs#L91.

So my goal with this issue is:

To check if maybe I missed something and there is a better way to do it
If there is no way to do it right now, would my solution be appropriate and I can open a PR in this repository?

Thanks
