Resolve "Add checking to the ROQ usage"

Closes #320 (closed)

• Adds testing which will cover the standard use cases (i.e. component mass sampling and chirp mass / mass ratio)
• No spins checking
• Adds methods to simplify calculating the minimum and maximums to the prior
• Adds testing and allows ROQ tests to be run locally or on CIT (using some predefined guesses as to where to find the bases)
