v6.0.1

Important In the 6.0 version the default package type has been changed to ESM modules by default. This should not affect usage, however since the output formats changed, a new major version is required.

Contributed:

• Add dev addresses for Frontier-based chains (Thanks to https://github.com/joelamouche)

Changes:

• Build to ESM by default (with cjs versions via export map)
• Allow addition or raw pairs on the keyring via {add, create}FromPair
• Extract re-usable json encryption/decryption functions
