hvfloat package causes error of macro already defined when loaded together with tabularray library `functional`

Question

This is a follow up question of Tabularray with footnotes from where the MWE is taken. The solution is great and I get the footnote in the table. however I cannot use it together with the package hvfloat which causes two errors:

1. ! LaTeX Error: Control sequence \fpAdd already defined.
2. ! LaTeX Error: Control sequence \fpSub already defined.

\documentclass{scrbook}
\usepackage[a4paper]{geometry}
\usepackage{hvfloat}
\usepackage{tabularray}
\UseTblrLibrary{counter}
\UseTblrLibrary{functional}
\makeatletter
\IgnoreSpacesOn
\tlNew \gFootNoteTl
\intNew \gFootNoteInt
\prgNewFunction \footNote {m}
  {
    \tlPutRight \gFootNoteTl
      {
        \stepcounter{footnote}
        \footnotetext{#1}
      }
    \prgReturn {\footnotemark{}}
  }
\AddToHook{env/tblr/before}{
  \intSetEq \gFootNoteInt \c@footnote
  \tlClear \gFootNoteTl
}
\AddToHook{env/tblr/after}{
  \intSetEq \c@footnote \gFootNoteInt
  \tlUse \gFootNoteTl
}
\IgnoreSpacesOff
\makeatother
\begin{document}
Some note\footnote{some note} before.
\bigskip
\begin{tblr}[evaluate=\footNote]{colspec={ll},hlines}
a line & a text\footNote{with a note} in the middle\
another line & another text\footNote{with another note} in the middle
\end{tblr}
\bigskip
\begin{tblr}[evaluate=\footNote]{colspec={ll},hlines}
a line & a text\footNote{with a note} in the middle\
another line & another text\footNote{with another note} in the middle
\end{tblr}
\bigskip
Another note\footnote{another note} after.
\end{document}

Ok, I found out that a solution is to load hvfloat after tabularray. But is there a better option?
