Volume boost

[Svk1190]

Describe your suggested feature

Problem:
Some videos have very low volume. Android does not give us an option to boost volume beyond 100%.

Solution:

1. VueTube can have an option to boost volume.
   This can be present in the settings page (increase volume 2x, 4x, 8x, 16x times).
2. Optionally, this feature can also be present in the VueTube volume slider. Pressing the volume up/down button opens the VueTube slider instead of the android volume slider (similar to MXplayer). The volume slider can be increased up to 1600% (or some other value higher than 100%).
3. Optionally, this feature can be combined with an equalizer, as discussed in issue Video Pitch #108 and shown in the image below.

If it ever gets added, maybe we should also be able to set the limit for max volume in the settings, I wouldn't want the volume button to be accidently pressed and turned to 1600%

Another idea that I had been considering would be a normalizer

I had requested the normalizer feature in #35.
