ECHO10 URL Type Modifications

[jenny-m-wood]

Describe the bug
ECHO10 only has a single URL Type field (not a Content Type, Type, and Subtype field). Providers sometimes provide a combination of the Content Type, Type, and Subtype in the single URL Type field, but pyQuARC does not currently support this.

To Reproduce
Steps to reproduce the behavior:

1. Open the test echo10 collection metadata file in pyQuARC
2. Enter a value of "VIEW RELATED INFORMATION : GENERAL DOCUMENTATION" or "PublicationURL : VIEW RELATED INFORMATION" in the Online Resources/OnlineResource/Type field
3. See GCMD inconsistency errors

Expected behavior
No error is given for echo10 records that provide a URL type that is a combination of the Content Type and Type or the combination of Type and Subtype separated by ":", " : ", ": ", " :" as long as the combination is in the correct GCMD hierarchy.

Outputs
Acceptable values (i.e. no GCMD error outputs) for echo10 would include:

"Type"
"Subtype"
"Type : Subtype"
"Type: Subtype"
"Type :Subtype"
"Type:Subtype"
"Content Type : Type"
"Content Type :Type"
"Content Type: Type"
"Content Type:Type"

Unacceptable values (i.e. GCMD error outputs) for echo10 would include, but are not limited to:

• Values not in the GCMD controlled list
• Combination of values that don't adhere to the GCMD hierarchy (e.g. "VIEW RELATED INFORMATION : DIRECT DOWNLOAD")
• "Content Type : Subtype"
• "Type : Content Type"
• "Subtype : Type"
• "Subtype : Content Type"

Checked on 10/3, still seems to be an issue
