Update Glide to the latest version

[cmargonis]

Hello everyone 👋

As we are trying to remove the use of jetifier from our project to decrease our build time, we noticed that iterable depends on a legacy Glide version 4.8.0 (latest stable is 4.16.0) . I noticed that it was added in this #508 PR and I'm not sure if there was any issue which prevented the use of newer Glide versions.

We would very much appreciate it if it could be updated (I can also open a PR updating it).
