Separate sndfile.hh implementation into C++ source 
This is required to be able to include
"audiographer/sndfile/sndfile_writer.h" in more than
one source file. which would otherwise lead to
duplicate symbol: AudioGrapher::SndfileHandle::..

Fix realtime export loudness normalization 
TmpFileRt::get_samples_written() returns the number of
samples written *to disk*. It is only valid after the FileFlushed
signal is emitted.

This fixes an assert() with Limiter and Analyzer being configured
with a too low total sample-count, leading to an overflow in
the analysis graph array.

Update analysis duration when post-processing 
This prevents the need to re-bin data in case silence is
trimmed at start or end of the export.

Overhaul export loudness normalization 
* Fix exporting multiple formats with different
  normalization settings or demo-noise settings
* Add true-peak limiter (based on x42-limiter dpl.lv2)
* Optionally use a limiter for loudness normalization
* Fall back to short-term loudness when normalizing
  material too short for integrating loudness.

Don't crash if ardour vamp plugins are n/a #8161 
This still assert()s in debug builds. Since those plugins
should always be available.

Prefer std::vector<> over C-style malloc/free** 
This fixes a potential out of bounds read `if (_dbtp_plugin[c])`
if c is larger than the allocated channel count.

c1910351a5 Revert "proper debug prints for Analyser" 
This reverts commit 9a281963e1.

audiographer cannot use symbols from libardour (cyclic dependency)
(only headers only are ok)
"DebugBits ExportAnalysis" symbol break windows and unit-test builds.

lib/libfftw3f.a(apiplan.o):apiplan.c:(.text+0x430): multiple definition of `fftwf_destroy_plan'

This is because static symbols in a .dll have no fixed address and
are mapped when loading the dll. Static functions in .exe do have a fixed
address.
With a header-only implementation the functions are provided
libardour.dll and ardour.exe
