This subroutine now used the new XML module to parge XML files. It also
used new subroutine read_binary_xml() to read binary files.

This subroutine is also responsible for detection if binary data are
compressed and encoded, and respectively decompress and decode them.

This commit does not change any functionality. It just prepares for
easier implementation of the compression of the restart snapshots.

The default compression levels correspond now to the default levels
defined by each compression format library.

This commit implements two data filters:
1) "shuffle" - reorganizes bytes to group most to less significant parts
together: |a1|a2|a3|b1|b2|b3| -> |a1|b1|c1|a2|b2|c2|a3|b3|c3|
2) "bytedelta" - additionally stores differences between subsequent
values: |a1|a2|a3|b1|b2|b3| -> |a1|b1-a1|c1-b1|a2|b2-a2|c2-b2|a3|b3-a3|c3-b3|
For large datasets, in particular in 3D, the compression ratio can be
significantly better after applying these filters.

For of all, update_shape now works with the conservative variables.
It is called in three points:
1) Just after the integration update or when the block were (de)refined.
2) Afted the boundary update.
3) If the unphysical cell correction is on, it is applied to blocks
which contain unphysical cells after they are corrected.

This makes the multiple block refinement extremenly slow, especially
when job is restarted with the maximum refinement level increased.

In the case of embedded integration method, the time step resulting from
the error could drop to very small values. In such situation, the next
time step is taken to a maximum value between the time step due to error
and the stability time step multiplied by the safe factor. By default
this factor is set to 0.01.

The meaning of these variables was inverted. Therefore, the limiting of
positive variables was not working.

It help with cross compilation and these flags can be added from the
command line, e.g., using
cmake <source_path> -DCMAKE_Fortran_FLAGS="-march=native".

The period is controlled by two parameters:
'injection_time_start' - the beginning of the injection period,
'injection_time_stop' - the end of the injection period.
