Usage of depreacted RPC calls that will soon be removed

[Woody4618]

Hey, there are bunch of RPC calls that are deprecated and will be removed very soon.
You can find the deprecated calls here:
https://github.com/anza-xyz/agave/wiki/Agave-v2.0-Transition-Guide

I searched your SDK for usage of these calls and looks like you are using

getConfirmedBlock
getConfirmedBlocks
getConfirmedTransaction
getConfirmedSignaturesForAddress2
getRecentBlockhash
getFees
getFeeCalculatorForBlockhash
getFeeRateGovernor
getSnapshotSlot
getStakeActivation

These calls will not be usable anymore soon after breakpoint when Agave 2.0 goes live.

You can find the all the usages in the code using this bash script:
https://gist.githubusercontent.com/cloakd/2366d9c5d415c27a1f26f10de0b8be93/raw/d0d3a25dda23586ba9704f7985fb06093032ec72/check_words.sh

Here you can find a replacement implementation for rust and JS client side for getStakeActivation:
https://github.com/solana-developers/solana-rpc-get-stake-activation

All other calls have replacement calls here:
https://github.com/anza-xyz/agave/wiki/Agave-v2.0-Transition-Guide

If you know users of the SDK would also be great if you could inform them about the deprecated calls so nothing breaks when the calls actually get removed on mainnet.

These are the usages in the code according to the bash script:
