CustomMode view frame issue

[songjisj]

Now MRProgress forces the provided custom view to be a square if using CustomMode, related code in manualLayoutSubviews in MRProgressOverlayView:

modeViewFrame = CGRectMake(modePadding, y, innerViewWidth, innerViewWidth);

Could you use the height which the custom view provides? Suggested change like:

modeViewFrame = CGRectMake(modePadding, y, innerViewWidth, self.modeView.frame.size.height);

Thank you.

You're right. Using the provided height would make much more sense here. Are you eager to put together a PR for that? That would be welcome.
