Moved read_attrb and read_icond to be called from job_init_fotran

 summa_SetTimesDirsAndFiles
 summa_defineGlobalData

The actors version now calls job_init_fortran as an interface which calls the SUMMA supplied subroutines.

Added the subroutines to the output_structure_routine for increased clarity.
Also removed the output structure specific file from the engine dir.

Replaced some messages with request statements.
This is to show the direct relationship the actors have in this request, instead
of relying on a send and send.

Used requests where it made sense in the actors. This is where the HRU
would send a message then wait for a response anyway. Instead of defining
messages for these cases we use request.

Attempting to make code more readable.

scalarCanopyLiq was not initailized properly. It now has the check in read_icond.f90

Fixed this by using the variables set by the container in the constructor.
These variables are checked whereas the input
into the constructor can cause problems with num_grus_per_partition becoming 0.

mDecisions would return an error, however the C++ side had no mechanism to
view or inspect the contents of the message.

A interface function in fortran was created to print the message.

Removing repeated code between this and the inner Summa the user clones

See merge request !4

Renamed some files that are replacement files for Actors version (so have same name as other code versions) and moved ascii_util.f90 (had allocation debugs, not Actors specific) into the regular code body

removing more files shouldn't need, moved them into summa code with compiler def. need to update cmake files to reflect this

add in compiler def ACTORS_ACTIVE to turn on some stuff so can move globalData, var_lookup, coupled_em, mDecisions into main code and out of Actors eventually. Also mod run_oneHRU to work with these changes and will move out into main code.

Do not need separate config file for specifying threads. Can use $SLURM_CPUS_PER_TASK

Uncomment of wallclocktime, also modified statistcs scripts

Scripts for going over data within Summa

HRU can now restart with timestep halved.

Changed the GRUinfo class to be just the GRU class.
This class now better reflects that it is the object that
the job actor holds. It will also contain the GRU actor that runs the simulation
portion of the program.

HRU timing was slowing down the code. It has now been removed.
The wall-clock-time of each hru is now the metric recorded.
