daedalus-v4l2 + daedalus-v4l2-dkms: bump to 872eec5 — PROTO_MAX_PAYLOAD 1 MiB (#20)

Browse Source 
Picks up reauktion/daedalus-v4l2 PR #20 (closes #19): wire-protocol
cap DAEDALUS_PROTO_MAX_PAYLOAD raised from 64 KiB to 1 MiB.
DAEDALUS_MAX_BITSTREAM follows; daedalus_fill_output_fmt now reports
OUTPUT_MPLANE sizeimage = ~1 MiB.

Fixes the Firefox YouTube avc1 SW-fallback observed on higgs when
any H.264 slice exceeded 64 KiB (routine on 720p+ streams).
libva-v4l2-request-fourier's S_FMT-driven OUTPUT-pool resize was
clamping back to 65484 and Firefox lost the slice; now the kernel
honours the larger sizeimage.

Both packages bumped to 0.1.0+r45+g872eec5-1:

  - daedalus-v4l2 (daemon): r43 -> r45.  Daemon-side allocations
    are dynamic, so the only growth is one ~1 MiB read buffer per
    daemon process at startup.
  - daedalus-v4l2-dkms (kernel module): r33 -> r45.  Skips the
    daemon-only bumps r37/r39/r41/r43 (no kernel/include change in
    that range) and lands the PROTO_MAX_PAYLOAD bump.

LOCK-STEP INSTALL REQUIRED: effective cap is min(kernel, daemon).
A stale kernel with a new daemon (or vice versa) still rejects
>64 KiB payloads.  apt/pacman should pick both up in one
transaction since they share the same upstream pin.

Wire-protocol value-only change in include/daedalus_v4l2_proto.h;
struct layout unchanged.  DAEDALUS_PROTO_VERSION stays at 0.
