By default, MacOS uses getopt from FreeBSD and not the GNU-based one.
Then "-o" and long options are not supported except if gnu-getopt
is installed.

Fixes #99

This provides a rebuild of all macOS executables. For reproducibility,
this was done entirely by `build_mac.sh`. I verified that different
machines produce bit-for-bit identical output. A build machine running
Xcode 16.2 16C5032a on macOS 15.2 24C101 was used.

These tools should run on macOS 10.13 and later. This version was
selected as it's the minimum macOS version that the xPack tools declare
support for.

A build of libusb is included, so that the provided `dfu-util` no longer
has an external dependency.

The universal structure was chosen for these tools to avoid changing
paths, anywhere they may be relied on. If desired, `build_mac.sh` can
also be used to produce single-architecture tools, even cross-compiling,
depending on the value of the `ARCH` variable.

The current released versions were selected:
 - libusb 1.0.27
 - dfu-util 0.11 (including dfu-prefix and dfu-suffix)
 - hid-flash from STM32_HID_Bootloader 2.2.2 (this program erroneously
   reports its version as 2.2.1), with a patch from
Serasidis/STM32_HID_Bootloader#68 (comment).
 - upload_reset from this repository at the HEAD of main
