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.

* jfjoch_broker: When in FPGA workflow (with PSI detectors) azimuthal integration might be forced to CPU - this will require more computational power, but it enables more integration bins and reports standard deviation of each bin.
* jfjoch_broker: Raise error if one is in FPGA flow and there are too many azimuthal integration bins.

This is an UNSTABLE release. The release has significant modifications and bug fixes, if things go wrong, it is better to revert to 1.0.0-rc.132.
* jfjoch_broker: Azimuthal integration mapping is generated with parallel computations, significantly reducing setup times
* frontend: Fix selection of FFTW in indexing settings
