System URL for CDT codesystem is incorrect when extracting out VSAC spreadsheets

[mholck]

Describe the bug
The VSAC Excel sheets for eCQM do not specify the system URL for the code systems so the tooling has a switch case statement for each codesystem name when extracting out the spreadsheets. The CDT codesystem URL is wrong

It is currently
case "CDT": return "http://terminology.hl7.org/CodeSystem/CD2";
but the system URL for CDT should be http://www.ada.org/cdt

To Reproduce
Steps to reproduce the behavior:

1. Download the VSAC eCQM spreadsheet for EC ec_only_unique_vs_20240502.xlsx
2. Run the tool using -VsacMultiXlsxToValueSet -pts=ec_only_unique_vs_20240502.xlsx -op=./output
3. See the system URL used for CPT

Update the CodeSystemLookupDictionary with the data in the "mapping" page of this spreadsheet:

ec_eh_oqr_unique_vs_20240502.xlsx

NOTE: This will need to be updated again once there is a resolution to the issues marked in "red" on that page, where VSAC is using a different URL for a code system than the official FHIR URL.
