Resolve missing spaces when long words wrap across a full line.

This resolves #162

Note: I had to disable "too-many-nested-blocks" to get it to pass pylint. I agree that the logic is difficult to follow, requiring a refactor of the whole thing to resolve (but I'm passing the technical debt forward for now).

My test code:

import terminalio
from adafruit_display_text import bitmap_label, wrap_text_to_pixels

text_string = "CircuitPython is a programming language designed to simplify experimenting and learning to code on low-cost microcontroller boards."
text_string=text_string+("\n\nWith CircuitPython, there are no upfront desktop downloads needed. Once you get your board set up, open any text editor, and start editing code. It's that simple.")

text_string = "CircuitPython is a programming language designed to simplify experimenting"

for width in range(20, 200, 5):
    text_lines = wrap_text_to_pixels(text_string, width, terminalio.FONT)
    print("width: {}".format(width))
    print('text_lines: {}'.format(text_lines))

while True:
    pass

Test result:

Looks good to me. Tested successfully on PyPortal 7.2.0.alpha-1 with the code given here and the wrap to pixels example in the repo.
