Precompilation issue with Julia v1.6

[Nosferican]

When precompiling PDFIO with Julia v1.6 it has just keep hanging for hours. Tested it with Julia v1.6.0-beta1 and PDFIO v0.1.10.

@Nosferican we will review the PDFIO compatibility issues with any release of Julia after the version is generally available.

I suspect the issue might be due to some change in the pre-compilation / artifacts system so it would be good to address it while in beta so it can be fixed for the release candidate (in case the issue is in Base or a stdlib and not in this package). The v1.6 beta has binary files to install from the website https://julialang.org/downloads/#upcoming_release. The beta version is also available to use in CI (see Discourse). It seems the issue is currently not known to the core maintainers as it was not included in the PkgEval summary (see Discourse).

It's already captured and can be seen in the logs:

The issue is known and already has been addressed in the trunk (#91) and now tagged as v0.1.11 and should work normally.

Since there was a failure across versions due to an access error to a test file download link, I fixed it and released version v0.1.11.

Any further issues with the Julia@1.6 will be looked at after the release.
