readFile() returns an overly long base64 string for videoFiles.

`const base64video = RNFS.readFile(videoUri, 'base64').then(res=> res).catch(err=>err)`

and when I log it, it goes super long that I can't even go to the starting point of it in my console so I just get its length. Turns out that the length of the b64 string for a .50 sec video is `600,000+` , 3secs video is `4M+`, and so on...

is this normal for this library to output such lengthy base64 string for just a short videos?

Just to add, the video size before converting is usually around 1mb to 3mb only
