Can't find variable: Buffer

[Sonwanseo]

Version of EOSJS 22.1.0

Describe the bug When I use PrivateKey, I got an error. The error message is "ReferenceError: Can't find variable: Buffer". This error causes because there's no buffer import statement.

(The Buffer is node.js built in object, so I don't understand why this error caused...)

To Reproduce If you need the example, please refer to my test project Clone my project, and execute 'yarn start' in terminal Please check 'src/PrivateKey.ts' file

Expected behavior No Error !
