Vlocity-Data-Package crashes sfp deployment

[Schuchie]

Describe the bug A vlocity-data-package can break the whole deployment process, when it contains a xml-file which isn't a metadata. In specific the pre and post deployers are not handling that case correctly.

To Reproduce Steps to reproduce the behavior:

1. Add a sfdx-package as type data
2. Insert a datapack with a random .xml-File
3. Try to deploy/create pool.

Expected behavior Deployment or Pool Creation should work without any issue. The pre-/post-deployers should not break with such a kind package.

Screenshots

Platform Details (please complete the following information):

• OS: Mac/GitHub
• Version [e.g. CLI Version eg: 1.6.6]: @flxbl-io/sfp/39.2.1 darwin-arm64 node-v18.20.3
• Salesforce CLI(sfdx cli) Version: @salesforce/cli/2.44.8 darwin-arm64 node-v18.20.3
• CI Platform: GitHub or local

Additional context Workaround: Just ignore the whole datapacks via .forceignore. (maybe the correct approach for datapacks?)

Following code runs into an error, when a xml file is contained in a datapack:

// sfp/src/core/package/packageInstallers/InstallPackage.ts:313
// sfp/src/core/package/packageInstallers/InstallPackage.ts:360

let componentSet = ComponentSet.fromSource(
    path.join(this.sfpPackage.projectDirectory, this.sfpPackage.packageDirectory)
);
