Bump rlp from 2.2.7 to 3.0.0

[dependabot]

Bumps rlp from 2.2.7 to 3.0.0.

Release notes

Sourced from rlp's releases.

rlp v3.0.0

rlp v3 is a breaking release with several important updates. Special thanks to @​paulmillr for the majority of this work in PR #90.

Dependencies

bn.js was removed in favor of BigInt support so the package now contains zero dependencies.

Default export

A new default export RLP now contains encode and decode.

You can now import and use RLP like this:

import RLP from 'rlp'
RLP.encode(1)

Uint8Array

Buffers were replaced in favor of using Uint8Arrays for improved performance and greater compatibility with browsers.

When upgrading from rlp v2 to v3, you must convert your Buffers to Uint8Arrays before passing in. To help, two new utility methods were added to ethereumjs-util v7.1.4: arrToBufArr and bufArrToArr. These will recursively step through your arrays to replace Buffers with Uint8Arrays, or vise versa.

Example:

// Old, rlp v2
import * as rlp from 'rlp'
const bufArr = [Buffer.from('123', 'hex'), Buffer.from('456', 'hex')]
const encoded = rlp.encode(bufArr)
const decoded = rlp.decode(encoded)
// New, rlp v3
import RLP from 'rlp'
const encoded: Uint8Array = RLP.encode(bufArrToArr(bufArr))
const encodedAsBuffer = Buffer.from(encoded)
const decoded: Uint8Array[] = RLP.decode(encoded)
const decodedAsBuffers = arrToBufArr(decoded)

Invalid RLPs

Increased strictness has been added to ensure invalid RLPs are not decoded, see PR #101.

[D4nte]

New version uses UInt8Array instead of Buffer. When trying to replace Buffer, did some hack around as other deps still use Buffer.

Best to remove buffer dependency properly first with See #337 and then do this upgrade.

[dependabot]

Looks like rlp is no longer a dependency, so this is no longer needed.
