updated pyhcl

[SebastianAtWork]

Hi, just a very small but significant update to pyhcl. See #63

[techdragon]

This build failure doesn't appear to be due to the code changes.

Unfortunately, this change does not remove all pyhcl errors -.- still getting others like:

@SebastianAtWork I've checked and it looks like it doesn't resolve my current issues either. Different error in my case, but its the same before and after the PR

[SebastianAtWork]

@techdragon Thansk for the checking. Then i will close this as it doesnt really help. I try to investigate further but I´m out of time (At Work) for now so it could take some time
