This reverts commit 2d33c20231 and
reapplies various patches for memory leaks.
The reason for the revert was a bug for a maximum duration interval
which caused sleep_for() to cause unpredictable behavior.
In all other places, the norm is to use `on-click-(middle|right)` but in
the mpris module, `on-(middle|right)-click` was being used which caused
clicks to malfunction if set to some custom commands
This commit allows better handling of ordering and exclusion of the tags in Dynamics tags.
It also becomes possible to choose the separator between the tags.
There were two main issues with fmtlib and C++20 mode:
- `fmt::format` defaults to compile-time argument checking and requires
using `fmt::runtime(format_string)` to bypass that.
- `std::format` implementation introduces conflicting declarations and
we have to specify the namespace for all `format`/`format_to` calls.
