Motivation and Context

This is a Pull Request to fix issue #128. Someone requested that you could change the alignments of the title text, description text as well as the image.

This PR solves that problem.

I tested on Xcode's 12.4 simulators of iPhone 8 and iPhone 12

Description

To change the alignment of title when instantiating a page FeedbackPageBLTNItem() set the page's .titleAlignment to be whatever you want (.left, .right, ect). If a user does not specify then the default alignment is center.

Similarly, to change the alignment of description use the .descriptionAlignment to set to desirable alignment And also to change the alignment of image use the .imageContentMode to set to desirable alignment

I'm thinking about doing some work on this library, but before I start I'm wondering will my pull request get approved? (assuming it is up to quality standards etc) or is this project orphaned now?
