Bug in _compile_headers_list

[alifbe]

In _compile_headers_list there is a check if the first character of wgnames is numeric or not. If it's numeric then it's assumed to be either cell/block coordinate (i, j, k) or region/aquifer index.

if lst[1][0].isdigit():

This will fail if for example the well name is starting with number.

Suggestion, add more check to the keyword, for example, ensure they are not well vectors (WOPR, WWCT, etc) and not a segment vectors (SOFR, SWFR etc)

if lst[1][0].isdigit() and kw[0] not in ['W', 'S']:
    nums = re.split(",", lst[1])
else:
    wgname = lst[1]
