Skip more exceptions for un-parsable files

[tanasegabriel]

One commonly used pattern is having a Terraform mono-repo. hcl2tojson is great for converting a bunch of .tf files to json, enabling easy parsing on the fly. It can however get tripped by readme files or git files:

./<redacted>/<redacted>/<redacted>/README.md
Traceback (most recent call last):
  File "/usr/local/bin/hcl2tojson", line 71, in <module>
    parsed_data = load(in_file)
  File "/usr/local/lib/python3.9/site-packages/hcl2/api.py", line 9, in load
    return loads(file.read())

    return hcl2.parse(text + "\n")

Rescuing more of these commonly encountered exceptions under the -s arg (skip) should enable more usage cases.
