Backend: detect dimensionality via other means, e.g. NDIM, instead of checking for acqu2s and proc2s files? about nmrpoise HOT 2 CLOSED

I think the simplest way is to add another cfhelper function getdim() :: int which returns the dimensionality (probably all it needs to be is an alias for getpar("NDIM") or something like that). After that it is trivial to change line 526 (same for line 540):

to

if p_acqu2s.exists() and getdim() == 2:

Actually, having getdim() will also help with #69 as then inside get1d_real() we can have

try:
    # ... code
except FileNotFoundError:
    if getdim() == 2:
        # raise helpful message from None
    else:
        raise

PARMODE = acquisition parameter for number of dimensions
PPARMOD = processing parameter for number of dimensions
