fix(dep): Bitstamp dependency relinked to fix `invalid nonce` error

Bitstamp plugin was occasionally throwing `Invalid nonce` error. Handled by relinking to [fixed](https://github.com/lamassu/bitstamp/commit/222e87a30eac8fa4f9b541d7b11c13556f6ca6ab) (and [forked](https://github.com/lamassu/bitstamp)) module.

Closes #1
