The grass.script.array module in GRASS 7 relies upon some changes
which were made to r.in.bin and r.out.bin, so it can't be used as-is.

It could be modified to work with the 6.x versions, although it would
require some changes. The main issues with the 6.x versions are:

1. You can't choose the output format (other than forcing integer
output with -i). The output is in the same format as the map, so you
would need to use "r.info -t ..." to determine the format of the data.

2. Integers are truncated to 16 bits.
