t.rast.aggregate.condition: Allow "running aggregations" #73
Description
Currently, t.rast.aggregate.condition produces non-overlapping granules just like t.rast.aggregate, meaning with a valid temporal granularity.
However, for our use cases, a running mean of valid values within a given time would be desireable.
A possible solution would be to:
a) set the granularity to a single day (in the command) and
b) add a temporal_buffer option where the input string has to be a valid granularity; granularities starting with a + indicate a "right side buffer" (following granules), starting with a - indicate a left side buffer (preceeding granules), and neither + or - indicate a symetric buffer around
Alternative options could be to have a buffer and offset option (probably most flexible,,,
