@doc """
Returns a map of `Cldr.Number.Symbol.t` structs of the number symbols for each
of the number systems of a locale.
## Options
* `locale` is any valid locale name returned by `#{inspect backend}.known_locale_names/0`
or a `Cldr.LanguageTag` struct returned by `#{inspect backend}.Locale.new!/`. The
default is `#{inspect backend}.get_current_locale/0`.
## Example:
iex> #{inspect(__MODULE__)}.number_symbols_for("th")

latn: %Cldr.Number.Symbol{
decimal: ".",
exponential: "E",
group: ",",
infinity: "∞",
