Purl is incorrect when the component name contains uppercase letter

[kennylam91]

It seems like the purl info is always lowercase even when the component name contains uppercase.
For example:

name": "org.latencyutils.LatencyUtils",
"externalRefs": [
  {
    "referenceCategory": "PACKAGE-MANAGER",
    "referenceType": "purl",
    "referenceLocator": "pkg:maven/org.latencyutils/latencyutils@2.0.3"
  }
]

As far as I know, maven package name is case-sensitive. Therefore its purl should be case-sensitive as well.

This issue is caused by a bug in packageurl-dotnet version 1.0.0.
The bug has been fixed in the latest version of packageurl-dotnet (package-url/packageurl-dotnet@7b27f39), so simply updating packageurl-dotnet to the latest version (1.3.0) should resolve this issue.

It seems that another bug in the latest version of packageurl-dotnet is blocking the update (#152).
