[KLC-818] Adds function to verify if account has the specified permis…

…sions (#6)

* feat: adds acc_has_perm function

* refactor: simplifies acc_has_perm function

* refactor(has_perm): changes return and removes params

- adds bool/int32 return to acc_has_perm functions
- removes unnecessary params on acc_has_perm functions
