allowzeropval and alternative for functions that compute p-valuesStarted NEWS.md.
Replaced some LaTeX symbols, \textrm -> \textnormal and lVert -> || (same for rVert), to fix LaTeX compilation issues in the r-oldrel-macos-arm64 when creating the PDF documentation file.

Added energy distance method energydist, which is computed naively.
