- adjust kernel parameters to new MVP settings
- ancillary ("copy-once") buffers have depth one
- frb kernels support arbitrary upchannelization factors
- correct upchan kernels for U=2 and U=4
Use `int`, `long`, `long long` etc. instead of `int32_t`, `int64_t` etc.
- use ringbuffer for input data - move phase matrix generation into F-Engine simulator - switch to `cublasHgemmStridedBatched` - some code cleanup
- rename file - check and set metadata
We do not need to quadruple-buffer the ancillary data products that are assumed to be constant in the CHORD pathfinder.
- Evaluate the argument of `CHECK_CUDA_ERROR` and friends only once. - Use parentheses. - Wrap in `do ... while(0)`
- support unsigned data types - reduce number of frequencies to 384 - some attempt at const-correct shared pointers
- support unsigned data types - add timing output - add option to shut down Kotekan after `n` frames
- use depth one for ancillary buffers - create FRB2 phase matrix - various updates
