Reading non-complaint grdecl files

My geologist gave me a .grdecl file produced by RMS which contains a property `ConnectedChannels_only`.

I am trying to read it with
```
with cwrap.open(file_path) as f:
property = resdata.resfile.ResdataKW.read_grdecl(f, "ConnectedChannels_only", rd_type=ResDataType.RD_INT)

```
This obviously fails the check from `rd_kw.py`

```
if kw:
if len(kw) > 8:
raise TypeError(
"Sorry keyword:%s is too long, must be eight characters or less."
% kw
)
```

I am wondering if it would be useful to reduce the strictness of the check with an optional flag to make the library useful for such .grdecl files?
