[ANN] lmpdecimal: another multiple precision library for Lua

[Luiz Henrique de Figueiredo <lhf@...>]

I've written another multiple precision library for Lua:
	https://web.tecgraf.puc-rio.br/~lhf/ftp/lua/#lmpdecimal
	https://web.tecgraf.puc-rio.br/~lhf/ftp/lua/ar/lmpdecimal-100.tar.gz

lmpdecimal is based on mpdecimal:
	http://www.bytereef.org/mpdecimal/

Checksum and other data available at
	http://web.tecgraf.puc-rio.br/~lhf/ftp/lua/release.txt
(BTW, if you use one of my libraries, check whether there is a newer version.) 

Like all my Lua libraries, this package is self-contained and also builds
out of the box in Linux and macOS, if Lua is installed in /usr/local.

Like all my code, lmpdecimal in the public domain and also under the MIT license.
Enjoy. All feedback welcome.
