Implement plugin callbacks

[MarkRivers]

Need to implement reading back TIFF or RAW files to do plugin callbacks.

TIFF files are just like Pilatus.

RAW files are problematic because they are not written until acquisition is complete, and a single file contains all of the images.

Perhaps we can issue the commands to write TIFF files from buffer while acquisition is in progress?

I asked Mark Tate:

One possibility for us to optionally get some or all of the images into areaDetector would be to collect data in "filestore 1 5" mode, but then periodically write some frames from the buffer to TIFF files while acquisition is still in progress.
Can the commands like storebuffers /path/filename tif_range low high or storebuffers /path/filename tif_single frame_number be issued while acquisition is in progress, or can they only be issued when acquisition is complete?

He replied:

It's very possible it could work.
You might also try the storebuffers command with the tif_last identifier. That will write the last image acquired (I've only used it to save a buffer after everything has stopped). The index is incremented as image frames are processed.
