fancy version of `zap-to-char' command

 This package provides two new commands `zzz-to-char' and `zzz-up-to-char'
 which work like built-ins `zap-to-char' and `zap-up-to-char', but allow you
 quickly select exact character you want to “zzz” to.
 .
 The commands are minimalistic and often work like built-in ones when there is
 only one occurrence of target character (except they automatically work in
 backward direction too). You can also specify how many characters to scan from
 each side of point.
 .
 This package uses avy as a backend.
