* fix: compiling on windows requires cosmic-icons in project root
crabtime provides crabtime::WORKSPACE_PATH to refer to the
CARGO_MANIFEST_DIR of the top level crate being built, which means when
building libcosmic directly, crabtime::WORKSPACE_PATH will work, but
when building it as a dependency of another crate,
crabtime::WORKSPACE_PATH will no longer refer to the path to libcosmic.
I don't think there's a good workaround, since when in the context of
crabtime, CARGO_MANIFEST_DIR refers to the path to the crate generated
by crabtime rather than to libcosmic.
This replaces crabtime with a simple build.rs script that generates a
file in OUT_DIR.
* fix: do not generate icon bundle for unix targets
---------
Co-authored-by: Michael Aaron Murphy <michael@mmurphy.dev>
calendar.rs had some left over icon! macro_rules macros referencing now
deleted files.
bundle::get was defined twice on non-unix platforms.
A known remaining issue is that projects using libcosmic need to have
cosmic-icons in their project root, since the crabtime macro uses
crabtime::WORKSPACE_PATH rather than the path to wherever cargo puts
libcosmic's git submodule.
