cs: Translate untranslated Czech emojis

• Uncomment and translate untranslated Czech emojis

Hello,
as my first contribution I translated and uncommented untranslated Czech emojis. I checked czech music notation and czech mathematical symbol guidelines. As it is my first attempt to contribute to github I find it very probable I messed something up - please do let me know, I will try to fix it.

EDIT: I should probably mention I am a native Czech speaker with NLP background.

I also managed to build and test it locally:

❯ ESPEAK_DATA_PATH=`pwd` src/espeak-ng -v cs -X "♯"
Replace: ♯   křížek 
Translate 'křížek'
  1	k        [k]

 36	ř       [R^]
 57	k) ř    [R^/]

 36	í       [i:]

 36	ž       [Z]

  1	e        [e]

  1	k        [k]

ESPEAK_DATA_PATH=`pwd` src/espeak-ng -v cs -X "*"
Found: '*' [hvjezJitSka]   $max3

There is no maintainer for Czech language. My I kindly ask @jaacoppi or @djphoenix as two of recent contributors for review/guidelines? Thanks. 😇
