oy_clean() steps

These should be dates/times:

• Date
• Start.Time
• End.Time

Journey.Action should be split into multiple columns, like:

• mode (train, bus, etc)
• from station
• to station

Charge is already numeric and zero. Credit will be money, so it should be numeric and NA should be 0? Maybe not; is there a conceptual difference between no charge for a journey (e.g. because of a season ticket) and credit, which is like one-off repayments? balance is numeric and okay.

Need some Note examples to see how they could be split to provide new columns of data.

• Handle no tap-out
• Handle journey action for updating a season ticket

In the July/August vignette example the charge and credit columns are numeric. I think credit should always be numeric (update oy_read() with as.numeric()?), but looks like charge can include season ticket (may need to separate this out into a separate column to leave charge with numeric values only).
