siunitx package is incompatible with bidi / XePersian

[vafakhalighi]

---

Brief outline of the feature request

It seems siunitx package is not compatible xepersian package. The decimal point does not change to the Persian decimal separator i.e. momayyez in \SI or \num sequences. Also \SIlist and \SIrange sequences have incorrect direction and should change words "and" and "to" into proper equivalents. Finally, xepersian package eliminates the degree symbol ° even in the latin environment.

Minimal example

% !TEX TS-program = XeLaTeX
% !TEX encoding = UTF-8 Unicode


\documentclass{article}
\usepackage{siunitx}
%\sisetup{detect-mode}  %detect-all

\usepackage{xepersian}
\settextfont{Yas}
\setmathdigitfont{Yas}

%\usepackage{fontspec}
%\setmainfont[Script=Arabic]{Yas}
%\usepackage{bidi}

\DeclareSIUnit{\calorie}{cal}
\begin{document}
یک کالری کوچک تقریباً برابر است با $4.2$ ژول (به‌طور دقیق $4.1868$ ژول)

\[\SI{1}{\calorie} = \SI{4.1868}{\joule}\]

\SIlist{0.13;0.67;0.80}{\milli\metre}

\SIrange{0.13}{0.67}{\milli\metre}

\num{3.45d-4} 

\ang{4,5} 

\ang{1;2;3} $\ang{1;2;3}$

\begin{latin}
\[\SI{1}{\calorie} = \SI{4.1868}{\joule}\]

\SIlist{0.13;0.67;0.80}{\milli\metre}

\SIrange{0.13}{0.67}{\milli\metre}

\num{3.45d-4} 

\ang{4,5} Where is the $^{\circ}$ (degree) symbol?!

\ang{1;2;3} $\ang{1;2;3}$

\end{latin}
\end{document}

Expected behavior
