[version 3.0.0] Major version bump

!! SDK VERSION 3.0.0 Release Branch !!
Changes from #145

ACC-based JWT Signing (V2): This new scheme simplifies the overall flow by baking into each dapp endpoint the required 

access control conditions directly. This means that there is no "store signing condition" step as dapp developers just write it into their dapp code and an additional check against the access control condition is performed there. 

When clients request for a signed JWT with claims of the specified access control condition, the signature of this JWT is only provided when the nodes determine that the user satisfy this access control condition. Read more in the spec here: https://www.notion.so/litprotocol/ACC-based-JWT-signing-V2-a4db1446bac54eea90b7ab08e5455246.

The BLS WASM (bls-sdk.ts) is entirely replaced with new code. Unit tests are added to this package.
The SDK no longer supports the jalapeno network moving forward. Developers can use the old SDK versions to continue using the old encryption and JWT signing schemes. serrano network is the new default.

Updated crypto package to be a lightweight wrapper over bls-sdk package with minor conversion logic.
Updated encryption package to replace the old encryption + JWT signing logic with the new schemes. This is becoming more a helper library over lit-node-client-nodejs and crypto.

Refactored params-validators to use a plugin-based approach with various *Validators.
Updated all manual tests in apps/html to use the new ID-based encryption and JWT signing schemes. You will notice quite a few test cases are removed since we no longer need to store encryption keys, or store signing conditions respectively.
demo-encrypt-decrypt-react:

Turned this into a TS project.

Updated this demo to use the new ID-based encryption scheme - just a encryptString and decryptToString call.
Implement demo-locked-express-app to demo the new JWT signing flow. Instructions in its README.md.
Made use of generics in a number of places, eg. IEither, SuccessNodePromises and benchmark()

Changes from #107

 - Adds support for new ECDSA implementation for
     - k256
     - p256
- Updates `ecdsa-sdk.ts` in `packages/ecdsa-sdk` with updated wasm bundle
- Adds  post build step to `ecdsa-sdk` for correcting a tic generation error
- Update `SIGTYPE` to include new ecdsa types
- Adds key recovery tests to `packages/crypto`

• Adds computePubKey to lit-core which wraps an implementation in crypto for interfacing with a new wasm module for deriving HD public keys: for reference the implementation which is compiled to WASM is here: https://github.com/LIT-Protocol/lit-ecdsa-wasm-combine/blob/main/src/combiners/hd_ecdsa/mod.rs
• Addition of claimKeyId method on lit-node-client-nodejs for deriving a key from an authMethod
  • Supports a new MintCallBack which is defined as async (params: ClaimKeyResponse): Promise<ClaimKeyResponse> which is called to route derived keys from a claim operation on chain.
• New ClaimProcessor abstraction for specifying arguments to a callback implementation for forwarding aggregated claim responses from nodes to the Chronicle chain which can be done by a relayer or contract client implementation within the callback.
