leonarski_fandClaude Opus 4.8 040cdeacf1 acquisition_device: give each device sole ownership of its buffers
The base AcquisitionDevice no longer allocates or frees frame buffers;
buffer_device is now just a non-owning view of addresses. Each subclass
owns its backing memory and the matching lifecycle:

- PCIExpressDevice mmap's the kernel DMA buffers and munmap's them in its
  own destructor (and on ctor failure), symmetric with MapKernelBuffer.
- HLSSimulatedDevice owns plain zeroed heap buffers it points
  buffer_device into, declared before the HLSDevice so they outlive the
  action thread that writes them. The buffers are page-aligned to match
  the real device's kernel DMA buffers - the modelled AXI datamover and
  FPGAIntegrationTest require aligned output buffers.

This drops the NUMA/mmap dance from the simulated path (not
performance-critical) - removing libnuma from acquisition_device - and
replaces the base-class cleanup that had to guess the allocation
strategy with a single clear owner per device.

This is an UNSTABLE release. The release has significant modifications for data processing - in case of troubles go back to 1.0.0-rc.144.

* jfjoch_broker: Improve azimuthal integration (add <I^2> calculation)
* jfjoch_broker: Fixes around indexing, aiming to handle multi-lattice crystals (work in progress, it is not fully integrated)
* jfjoch_writer: Save mean(I), stddev(I), and count(I) for each azimuthal bin
