Unable to use offline key with compiled binary

[ARolek]

I just tried following your blog post, Compressing and Optimizing PDFs in Pure Golang using UniPDF using a compiled binary with my offline key. For example:

UNIDOC_LICENSE_FILE="unidoc_license.key" UNIDOC_LICENSE_CUSTOMER=<customer_name> unipdf license_info

And I get the following output:

License: License Id:
Customer Id:
Customer Name: Unlicensed
Tier: unlicensed
Created At: 30 August 2023 at 17:23 UTC
Expires At: Never
Creator:  <>

The keys I'm providing are used in production so I know they're correct. I then dug into your source code and I found the bug:

unipdf-cli/pkg/pdf/pdf.go

Lines 17 to 25 in b3344a3

	func SetLicense(licensePath string, customer string) error {
	// Read license file
	content, err := ioutil.ReadFile(licensePath)
	if err != nil {
	return err
	}
	return unilicense.SetLicenseKey(string(content), "")
	}

If you look at line 24, the customer name is hard coded as an empty string. Change that line to pass the customer variable and everything works.
