9f1e206b34 feature: Add lc3_encoder_disable_ltpf 
LTPF requires a lot of processing power, so disabling it might be
required for embedded low-performance devices.

7558637303 python: remove semicolons 
While mostly harmless, random semicolons in Python can be a bit
distracting when reading the code, especially when one uses a syntax
highlighter that flags them as errors.

5e528fc543 build: fix rpath issue 
While packaging for homebrew, I ran into some rpath issue when building the tools.

```
$ /opt/homebrew/Cellar/liblc3/1.1.0/bin/elc3 -h
dyld[72986]: Library not loaded: @rpath/liblc3.1.dylib
  Referenced from: <1B4E9174-0A9C-3907-8487-40BBBE5B52CB> /opt/homebrew/Cellar/liblc3/1.1.0/bin/elc3
  Reason: no LC_RPATH's found
Abort trap: 6
```

This patch is for fixing the rpath ref issue.

f48f0ff4d7 test: Add numpy include path 
test/setup.py currently expects the numpy header to be in the
system include path. This is not always the case,
numpy.get_include() is used to add the include path for those cases.

3f05fcb8f2 python bindings: build/install via integrated meson support 
The meson build system has builtin support for python packaging, and
unlike hatchling it is spec-compliant. Additionally, meson is already
responsible for building the shared library itself, which the python
build backend can then distribute inside the wheel. This allows shipping
a wheel that can find its own liblc3.so via ctypes and doesn't require
passing paths to the library around, nor to install both separately and
hope that this works.

e67bb2d07d wasm: Add a wasm liblc3 library 
The wasm library is automatically built when the compiler target
is set to wasm32 in bin/liblc3.wasm.

This can be done using `make CC="clang --target=wasm32"`.

This wasm library doesn't have any import and expose all liblc3
functions.
