@spec slice(binary(), MetaLogger.Slicer.max_entry_length()) :: [String.t()]

Returns sliced log entries according to the given max entry length.

Ensures that all slices are valid UTF-8 strings by not splitting multibyte characters. If the entry is smaller than the given max length, or if :infinity is given as an option, a list with one entry is returned. Otherwise, a list with multiple entries is returned.
