Motivation and Context

Use quality param for video capture on iOS too.
Previously no configuration was done about it, meaning that the quality used for capture was medium as iOS default value.

Here is my suggested implementation based on previous PR #162 by @larrybahr with changes after my review and more tests + aligned default to 1 for iOS as it is for Android.

Description

Follow iOS logic about video quality: doc

quality value of 0 for UIImagePickerControllerQualityTypeLow, 0.5 for UIImagePickerControllerQualityTypeMedium, or 1 for UIImagePickerControllerQualityTypeHigh.

For any other value or when quality param is not provided we use UIImagePickerControllerQualityTypeMedium UIImagePickerControllerQualityTypeHigh.

Testing

Confirmed the switch-case resolution with various quality values: 0, 0.5, 1, 2, 'foo', false, undefined, and without any captureOpts.
