[#394] sample mut uninit

[elfenpiff]

Notes for Reviewer

• Fixes the problem that uninitialized samples can be sent by introducing a SampleMutUninit struct that does not offer a send method
• Renames the method send_sample into send since it was weird to read send_sample(std::move(sample)), this is much cleaner send(std::move(sample)).
• The introduction of the new class needed an adjustment on the C API level - here we always use uninitialized samples
  • SampleMut has no C binding, the C++ implementation is done directly via the C API, otherwise it would be much more code on the FFI layer
