Why does this happen: `float` data should be aligned to 4 bytes [1], but this is not guaranteed when the truth data is `uint16_t` and is in the buffer before the weights data
Solution: re-arrange the buffer so that the weights data (type `float`) comes before the truth data (type `uint16_t`), essentially making it so that the `float` data is correctly aligned to 4 bytes

* typo
* - added compile time information to audio object. Not convinced this is needed actually. I'm perfectly happy just using the ffmpeg::frame object. I'm pretty sure I'm the only user who cares about audio.
- created resizing_args and resampling_args
* smaller videos for unit tests
* shorter videos for unit tests
* - decoder and demuxer: you now resize or resample at the time of read. therefore you don't set resizing or resampling parameters in constructor, but you pass them to read()
- added templated read() function
- simplified load_frame()
* inherit from resizing_args and resampling_args
* reorganised the tests to segragate decoding, demuxing, encoding and muxing as much as possible
* much more basic example
* demxing examples split
* examples
* fixing examples
* wip
* Fix load_frame()
* added frame - specific tests
* - makes sense to have a set_params() method rather than constructing a new object and moving. I mean, it works and it absolutely does the right thing, and in fact the same thing as calling set_params() now, but it can look a bit weird.
* notes on defaults and good pairings
* Update ffmpeg_demuxer.h
Watch out for `DLIB_ASSERT` statements. Maybe one of the unit tests should build with asserts enabled.
* Update ffmpeg_details.h
* Update ffmpeg_muxer.h
* WIP
* WIP
* - simplified details::resizer
- added frame::set_params()
- added frame::clear()
- forward packet directly into correct queue
* pick best codec if not specified
* added image data
* warn when we're choosing an appropriate codec
* test load_frame()
* - for some reason, you sometimes get warning messages about too many b-frames. Resetting pict_type suppresses this.
- you can move freshly decoded frames directly out.
* callback passed to push()
* I think it's prettier this way
* WIP
* full callback API for decoder
* updated tests
* updated example
* check the template parameter is callable and has 1 argument first before getting it's first argument
* Potential bug fix
* - write out the enable_if's explictly. It's fine. I think it's clear what's going on if someone cares
- guard push() with a boolean which asserts when recursion is detected
* pre-conditions on callbacks: no recursion
