Reset ansi colour

[tmck-code]

Context

pokesay can correctly display coloured text as of v0.14.0 🎉

If this text does not contain a colour reset code (\e[0m) at the end of every line, then the colour will bleed out into the bubble and surrounding terminal

before	after

Changes

• Insert the ANSI colour reset code at the end of every line
• correct a typo: SingleWidthCars -> SingleWidthChars
• Remove a redundant tab -> space conversion
• Rearrange the if statement in printSpeechBubbleLine
  • only need 2 branches - "needs padding" and "omit the bubble on the RHS"
  • (if the lines are exactly equal i.e. no padding, the strings.repeat function will return an empty string if the repeat value is 9)
