…ton icon when hint text is blank/null (crosspoint-reader#884)

## Summary

* **What is the goal of this PR?** (e.g., Implements the new feature for
file uploading.)

Empty Button Icons (I.E. Back button in the home menu) were still
rendering the full sized white rectangles going passed the boarders of
the little button nub. This was not visible on the home screen due to
the white background, but it does cause issues if we ever want to have
bmp files displayed while buttons are visible or implement a dark mode.

* **What changes are included?**

Made it so that when a button hint text is empty string or null the
displayed mini button nub does not have a white rectangle extending
passed the bounds of the mini button nub

## Additional Context

* Add any other information that might be helpful for the reviewer
(e.g., performance implications, potential risks,
  specific areas to focus on).

Having that extended rectangle was likely never noticed due to the only
space where that feature is used being the main menu where the
background is completely white. I am working on some new features that
would have an image displayed while there are button hints and noticed
this issue while implementing that.

One other note is that this only affects the Lyra Theme

#887)

## Summary

* **What is the goal of this PR?** (e.g., Implements the new feature for
file uploading.)

Implements new feature for viewing .bmp files directly from the "Browse
Files" menu.

* **What changes are included?**

You can now view .bmp files when browsing. You can click the select
button to open the file, and then click back to close it and continue
browsing in the same location. Once open a file will display on the
screen with no additional options to interact outside of exiting with
the back button.

The attached video shows this feature in action:

## Additional Context

* Add any other information that might be helpful for the reviewer
(e.g., performance implications, potential risks,
  specific areas to focus on).

The changes implemented in #884 are also present here as this feature is
actually what led to me noticing this issue. I figured I would add that
PR as a separate request in case that one could be more easily merged
given this feature is significantly more complicated and will likely be
subject to more intense review.
