Custom Acronyms for ToCamel && ToLowerCamel

Often times text can contain specific acronyms which you need to be handled a certain way. Out of the box strcase treats the string "ID" as "Id" or "id" but there is no way to cater for every case in the wild.

To configure your custom acronym globally you can use the following before running any conversion

import (
    "github.com/iancoleman/strcase"
)

func init() {
    // results in "Api" using ToCamel("API")
    // results in "api" using ToLowerCamel("API")
    strcase.ConfigureAcronym("API", "api")
    
    // results in "PostgreSQL" using ToCamel("PostgreSQL")
    // results in "postgreSQL" using ToLowerCamel("PostgreSQL")
    strcase.ConfigureAcronym("PostgreSQL", "PostgreSQL")

}
