Processor to find and replace patterns in field(s)

[zelima]

As a dpp user, I want to be able to find some strings and replace/remove them, so I don't need to do it manually.

As a dpp user, I want to be able to replace certain patterns from field values so that I'm able to clean my data as I want.

For example one of the field in my data may have anchors for footnotes:

year,country,number,
2000,XXX,12345
2001 (2),XXX,12345

Acceptance Criteria

• [x] I'm able to define one or more patterns to find and replace with
• [x] I'm able to define regex to find pattern

Tasks

• [x] write spec
• [x] new processor find_replace
• [x] tests
• [x] README
