Expand dataset so each row represents a day

[lchski]

For that day, each of the following should be correctly identified:

• Type of service (role_type_of_parliamentarian)
• Minister (role_minister)
• Critic (role_critic)
• Riding/senatorial division (seat_riding_senatorial_division)
• Political affiliation (political_affiliation)

Some caveats:

• This will be some “fun” data processing 😛
• A quick scan shows that role_critic doesn’t always have specific day values, only year values. This likely applies to values in other columns, too.
• Some of the political_affiliation values have ( or ) in them (e.g. Conservative (1867-1942) (1911/09/21 - 1915/04/15) for Aikins, James Albert Manning)
