Previously, we left out the dependency of the QSTR header on
`modules.h`.  This was done to prevent rebuilds of the entire
MicroPython sources whenever a Pycardium module is changed. This
leads to issues where QSTRs got out of sync and weird errors like
the following could happen:

    import foo_module

    Exception: No module `abc_def` (a different string than expected)

Attempt to fix this by only updating the QSTR header when the
module-header actually changes.  For this, a few workarounds are needed:

- Replace symlinks with actual copied files so timestamps change on
  updates.
- Add a hack so meson picks up on the dependency of the file in genhdr/
- Rename the outer file so older meson versions don't complain about
  multiple targets with the same name.

756c13df epicardium/rtc: fix numerically unstable subsecond decoding

         the subsecond encoding function from epic_rtc_set_milliseconds
         and the corresponding decoding function from
         epic_rtc_get_milliseconds are not numerically stable.

         i.e., encoding 5 milliseconds to 20 subsecs and immediately
         afterwards decoding that yields 4 milliseconds.

         Adding a bias of 999 (0.24 milliseconds) to the decoding
         function makes it numerically stable, while never decoding any
         subsecond value to more than 999 milliseconds.

The outer two stripes should be twice as wide as the middle stripe.

Otherwise, /card10.bin would be writable :)
