feat (functionality): change special String cases

Able to convert given string to equivalent pascal, camel,
snake and kebab case.

Change the strings according to following examples,
	"clAsS#1_nAmE" to pascal case is "Class1Name"
	"vaRiAbLe#1_nAmE" to camel case is "variable1Name"
	"DO_fuNC@$01 nAmE" to snake case is "do_func_01_name"
	"DO-fuNC@$01 nAmE" to kebab case is "do-func-01-name"

Resolves: #126
