Use CW instead of Terra wherever possible (#63)

There are still some places that Terra is mentioned such as
deploy scripts and available networks.
We should update them later.

 This repository contains an example contract that demonstrates how to read the Pyth price from the Pyth on-chain contract.
 The example [contract](src/contract.rs) has two functions:
 
 * `instantiate` sets the Pyth contract address and price feed id that the contract uses.
   This function is intended to be called once when the contract is deployed.
-  See the [Terra SDK README](../../pyth-sdk-terra/README.md) for the list of possible price feed ids.

 When deploying the contract, you may encounter gateway timeout or account sequence mismatch errors.
-If this happens, check terra finder to determine if your transaction succeeded -- sometimes transactions succeed despite timing out.
