casting_time data is wrong

[tylereed]

It looks like the data for casting_time in v2 of the spell data is bad. 9 of the spells have a time of 'reaction'. The rest of them have a casting time of 'action'.

Looking at Misty Step, which should have a casting time of "Bonus Action", the api returns 'action'.

It seems to me that the converter function get_casting_time isn't converting from v1 to v2 properly.
