We do not have separate messages for the state machine anymore
but derive all the information from the stream itself. This
also causes the statistics to change -> it is now run
oriented instead of statistics modulo.
We do not rely on start_pulse_id and pulse_id_step to
calculate the next image as we don't care which image this
will be - we write whatever we receive. This will allow us
to use an external driver for the pulses we desire to write.
In comparison with the normal writer, the block operations
have been dropped and the buffering of metadata is not sparse
anymore. Direct chunk writing used for data and buffering +
dump at end for metadata.
The difference between the normal and the LiveImageAssembler
is that the live one can process each image individually,
sacrificing storage performance for writing flexibility -
the user can decide live exactly which frames to write.
Since we are always using this recorders in the context of
Jungfraus, we should start naming things in this context as
well. Instead of root_folder we will be using detector_folder
(as root of the buffer on disk for a specific detector) and
module_name instead of device_name (to specify one module
inside the detector).
The binary reader reads 1 frame at a time from a module - the
difference being loading 1 image instead of 1 block of images.
This will allow to set the offset and pulse_id increment easily
without complicated internal buffer calculations.
