Query transactions by type.....and other transaction elements

[matmaxgeds]

Is your feature request related to a problem? Please describe.

At the moment, not all transaction elements are available - I quite often want to query only some transactions......this is designed to work with the potential new transactions endpoint #366

Describe the solution you’d like

At the moment you can only query by transaction receiver/provider: https://datastore.codeforiati.org/docs/api/#transaction so it would be great if more of the elements were included - my personal priority was transaction type.

Describe alternatives you’ve considered

I just have to do this post-query at the moment

Additional context

I was trying to export all transaction-type = 1 or 11 for a country........
