Coil artifacts have same/duplicate manifest package names

[ZacSweers]

Describe the bug
Reported on AGP 4.1 alphas

[io.coil-kt:coil:0.10.1] /Users/zsweers/.gradle/caches/transforms-2/files-2.1/17ebe6f408a1cb3fba8c675f723aa6b6/coil-0.10.1/AndroidManifest.xml Warning:
        Package name 'coil.base' used in: io.coil-kt:coil:0.10.1, io.coil-kt:coil-base:0.10.1.

Expected behavior
They should have different package names

To Reproduce
Build with AGP 4.1

Version
0.10.1

Can send a PR if you want, but need a new package name. I think single-entry package names (i.e. just coil) still aren't allowed, but maybe coil.core? Or make them all io.coil ± subpackages?

@ZacSweers Ah thanks for the heads up. What do you think about coil.default and coil.base (same as the Gradle module names)? Definitely open to a PR!

EDIT: Looks like coil.default isn't valid. 🤔 coil.core (for the singleton module) sounds good for the moment to unblock building with AGP 4.1.

yeah can't use java keywords in it either :)
