Subject: [PATCH] refactor: update pkg caller identification in initialize
 (#138)

Replace the usage of `runtime.Caller` with the faster,
zero memory allocation, and convenient `loc.Caller`
in `teler.New`.

This change introduces a performance improvement,
especially when using the `nikandfor_loc_unsafe` build tag.
