Bump ethereumjs-util from 6.2.0 to 7.0.0

[dependabot-preview]

Bumps ethereumjs-util from 6.2.0 to 7.0.0.

Release notes

Sourced from ethereumjs-util's releases.

v7.0.0 - Typestrict API / Crypto Update / Dev Improvements

This release comes with significant changes to the API, updated versions of the core crypto libraries and substantial developer improvements in the form of a refactored test suite and API documentation.

API Changes

Changes to the API have been discussed in Issue #172 and are guided by the principles of:

• Make the API more typestrict
• Be less ambiguous regarding accepted values
• Avoid implicit type conversions
• Be more explicit on wrong input (just: throw)

While the implemented changes come with some additional need for manual type conversions depending on the usage context, they should finally lead to cleaner usage patterns on the cosuming side and a more predictable, robust and less error-prone control flow.

Some note: for methods where Buffer usage is now enforced you can use the Bytes.toBuffer() method for conversion.

Account Module

Enforced Hex Prefixing for Address Strings

PR: #241

Hex prefixing is now enforced for all address string inputs and functions will throw if a non-hex string is provided:

• Account.isValidAddress()
• Account.isZeroAddress()
• Account.toChecksumAddress()
• Account.isValidChecksumAddress()

The Account.isPrecompile() method was removed from the code base, PR #242

Enforce Buffer Inputs for Account Methods

PR: #245

Implicit Buffer conversions for the following methods have been removed and Buffer inputs are now enforced:

• Account.generateAddress()
• Account.generateAddress2()
• Account.pubToAddress()
• AccountprivateToPublic()
• AccountimportPublic()

Bytes Module

Typestrict Methods and Type-Explicit Method Split-Up

PR: #244

• Enforced Buffer input for Bytes.setLengthLeft(), Bytes.setLengthRight()

... (truncated)
