What's in this PR?

This PR adds a new api method to retrieve frames through ffprobe
It also adds a support for additional options allowing more custom calls
As an addition, as last method has been added to StreamCollection and FrameCollection for easier retrieval

I also regenerated the api doc which was largely outdated, using sami 1.4.1, feel free to hide this commit to make the review easier

Why?

Frames information can be needed in some cases (see example below)
Additional options allow some filtering directly within ffprobe which would otherwise require iteration and operations on our output and therefore defeat the purpose ffprobe having such features

Example Usage

Retrieving the starting byte and ending byte matching a timestamp interval in an audio file (needed to generate audio previews without persistence)

$probe = FFProbe::create();
$filepath = 'tests/files/Jahzzar_-_05_-_Siesta.mp3';

// Now we can do
$options = array('-select_streams a', '-read_intervals 00:08%00:18');
$frames = $probe->frames($filepath, $options);
$startByte = $frames->first()->get('pkt_pos');
$endByte = $frames->last()->get('pkt_pos');
echo sprintf('The byte interval closest to 08 -> 18 seconds is %d -> %d', $startByte, $endByte);

// Outputs: The byte interval closest to 08 -> 18 seconds is 193618 -> 433735

Backward compatibility

No BC break.
Interfaces are left unmodified and public api methods only offer a new parameter with a default value not altering the behavior in any way
Unit tests have been updated accordingly
