Expose remaining RPC methods

[ChaoticTempest]

There's currently a couple RPC methods not being exposed from Worker such as:

• chunk
• gas price (Gas price not available from block #146)
• status

We should be exposing these where they make sense, and this issue also depends on #129 to be resolved first for the most consistent API

looking forward for gas price api!! i can't test methods which transfer NEAR to user with good assertions because we can't account for gas!

Are there any updates on this issue? @ChaoticTempest

[ChaoticTempest]

Both gas_price and chunk have been implemented and are available. Network status has not been implemented

[jaswinder6991]

Do you have the PR's handy for gas_price and chunk that I can refer to. I will also look for them myself.

[ChaoticTempest]

gas price you can find here: #218
chunk you can find here: #234

Also, note for anyone trying to implement status. We can't expose the status type coming from near-primitives as that would leak internal details which are still unstable and are likely to change
