Inject web3 library: support ethers v5, ethers v6, and viem

[MantisClone]

Towards #1202

Problem(s)

1. Our packages require ethers v5. This is a problem because:
2. Large dependency so it's slow to download and install
3. Some users want to use other web3 libraries (ethers v6 or viem)
4. We don't support viem, a smaller and more performant web3 library than ethers with a more stable API.

Solution

Develop a web3 library interface. Make the user inject their web3 provider. Support both ethers and viem. Maybe the interface matches viem, and then we just write a wrapper so that ethers can look like viem.
