lcdnums fonts are missing "space" in character set

Trying to print right adjusted numbers with the lcdnums fonts is quite difficult as there is no "space" i.e. "blank" character in the set.
Space is not missing. Fonts are required to be a contiguous set of characters by the glcd font standard. Here is a comment from the creator of the font.
This font is not a complete character set. The font only contains the characters: '+', ',', '-', '.', '/', '0', '1', '2', '3', '4', '5', '6', '7', '9', ':'
I understand the issue and for this I have modified the lcdnums14x24 font to contain 10 dummy characters so that I can reach the space at 0x20.
This makes the font slightly larger but allows simpler coding.
I use your great library to show the weight on a DIY scale and I convert the float from the HX711 module with dtostrf( weight, 7, 1, strBuf ) so that I can use overwriting at a fixed position which gives me the least flicker on the display.
Without the 'space' character I would use much more code to get the display digits right justified.
