[WIP] Add tx list request and response

[drbh]

I was hoping to get a better understanding of the project and the flow to add new features. Got stuck on the serialization of the response items. Once I fully understand how to parse these responses there are a few other features I would like to help add! Can we get this PR resolved and the responses serialized correctly?!

Changes

1. example account to 82258967750773ea090d125f9aeb9b9e42f6c7ff6df0742336992bfc52b4096a since it was causing the example app to panic.
2. Added GetTransactionList and used the existing Request Item types.
3. Added to the tx.go file to support Transaction Lists

Help Needed

With FromTransactionListBlob not exactly sure how to serialize the response. Also with FromTransactionListResourceBlob

Thanks for the PR already!

I don't have time to look at the code right now, maybe next week.

The CI build failed because of the linter. See https://travis-ci.org/philippgille/libra-sdk-go/builds/558352696#L631

Regarding the decoding you may find some inspiration here:

• https://github.com/perfectmak/libra-core/blob/f4aad96a84b5986e15e4d9996ad49e238e2497c5/lib/client/Decoder.ts#L80

And could you please change the target branch from master to develop? Thanks!

Hey @philippgille,

I've made some good progress on pulling the TX list. Heres what a single transaction from a transaction list looks like

[
{
    "raw_bytes": "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",

I think the raw_bytes need to be decoded as you noted above - if you could help me get started that would be awesome! otherwise I'll take a stab at it next chance I get 👍

[philippgille]

An extra type for a transaction list that only contains a slice of transactions is not necessary I think.

Great to see you're still working on it!

Did you check out the TypeScript SDK I linked to in the previous comment for clues regarding the decoding? I didn't check it in detail yet, maybe I can have a more thorough look soon.
