MergeRecords can support array.Float64 sort?

[jicanghaixb]

MergeRecords function is very useful. Thank you for providing this function. but now not support *array.Float64 sort, can we support it?

Also, could we add a reverse sorting function MergeReverseRecords？

Supporting float64 shouldn't be too difficult to add to the Less function: https://github.com/polarsignals/frostdb/blob/main/pqarrow/arrowutils/merge.go#L95-L142
We'd happily accept if you want to send a Pull Request.

Adding reverse sorting to merging seems possible. We would need to discuss what the API change would look like or if we should add another function like you proposed.

Do you have an example where sorting the records first and then merging the record wouldn't work?
