MTP-1537: Removed duplicated dependencies

Removed dependencies already provided by `mtp-common` package.

NOTE: `pysftp` and `bankline-direct-parser` seem to be unique of this
application so it's fine to leave these here as additional requirements.

mtp-common-10.1.0 dependencies: https://github.com/ministryofjustice/money-to-prisoners-common/blob/905023f9e99468dd90d984a8ecc1c25deb6c08ec/setup.py#L18-L35
