add an option to choose an ASCII font

[cpanato]

What type of PR is this?

/kind feature

What this PR does / why we need it:

• add an option to choose an ASCII font
  the lib we use to print ASCII fonts has several fonts available to use right away.
  So we can enable that when configuring the version in the application

For example:
