chore: improve polycli fund

[leovct]

Description

• chore: migrate from web3 library to go-ethereum.
• feat: Implement a Funder smart contract to be able to bulk fund wallets in one transaction. It speeds up the funding process by a lot. 🚀
• chore: refactor flags, check flags in PreRunE and move flag logic to app.
• feat: enable to fund wallets specified by user
• feat: enable to derive wallets from private key
• chore: use RunE instead of RunE when running the fund command.
• chore: update --eth-amount in polycli loadtest. Users can now specify the amount in eth instead of having to specify the hexadecimal representation of the amount in wei.

Jira / Linear Tickets

• DVT-1114 - migrate to go-ethereum lib.
• DVT-1116 - enable to fund wallets specified by user.
• DVT-1115 - enable to fund wallets derived from private key.

@rebelArtists A couple of changes since last review.

• Modified the amount flag.
• Enabled to fund addresses specified by user.
• Enabled to derive wallets from mnemonic (used by default).
• Minor stuff (clean up, refactor, etc.)

nice job, lgtm 🔥

tried testing it out with the sample commands in the PR description:

polycli fund --wallets 20 --verbosity 500

but realized, the flag has been changed from wallets to number lol.
