New FFT initialization functions to make it easier for the linker
to optimize the code size when the library is used as a static
library and can't be rebuilt.
Compilation directives for code size optimizations have been removed.
Fixed shadowed variables in assembly macros for Cortex-M convolution
Fixed type promotions in _f64 matrix and transform code

Include header for arm_accumulate_f64, same as how _f32
works to address the following GCC warning when enabled:
Source/StatisticsFunctions/arm_accumulate_f64.c:97:6:
warning: no previous declaration for 'arm_accumulate_f64' [-Wmissing-declarations]
97 | void arm_accumulate_f64(

In relation with issue #58
When HELIUM, MVEF or MVEI are used as cmake options, the option
LAXVECTORCONVERSIONS can be set to ON or OFF to enable / disable
lax vector conversions in GCC or ArmClang.
Currently, CMSIS-DSP won't build if lax vector conversions are disabled.
The option is ON by default.
Corrected issue with RFFT APIs
Added some features to compute graph
Improved documentation related to RFFT
Changed how Python wrapper is built (to prepare fro future
evolution).
Regular functions for use with tone detection and noise estimation.
Flat-top windows for estimation of tone amplitudes.
Parameters of the windows are given.
Kaiser window missing (Bessel function not available in the library).
No f16 implementation since it is not accurate enough. It is better
to compute a f32 window and convert to f16 after.
Some CMSIS-DSP code does not explicitly convert between vectors of
different numbers and types of elements. While some other compilers
default to implicitly converting vectors, gcc does not do this unless
explicitly enabled.

Saturation problem in arm_absmax_no_idx_q(7|15|31)
Difference of behavior for absmax_q(7|15|31) between reference and code:
reference is first max found. Code was last max found.
Corrected issues with arm_fir_decimate and arm_fir_interpolate
Corrected issues with real FFTs in the wrapper
Added a customization option for the FIFO class in compute graph.
Added Python tests for the corrected functions.
Table configuration issue with RFFT Fast F32 and F16
The define use to include or exclude the bit reverse table is different
for scalar and MVE versions. The test was not covering both cases.
