Description:
Liblouis is an open-source braille translator and back-translator. It
features support for computer and literary braille, and supports
contracted and uncontracted translation for many languages.

LibLouis is used as a web assembly module.

Local Modifications: * Add liblouis_wrapper.js, a js wrapper to wasm binary.  *
Add tables.json, a list of tables with metadata.  * Add cvox-common.cti with
common definitions for all tables mentioned in tables.json.  * The web assembly
module is compiled by using emscripten.  As of writing, the fastcomp sdk (the
older compiler) picks up on LibLouis' C exports while the non-fastcomp compiler
does not.

Use the following commands to set up your environment:
cd <PATH_TO_EMSDK>
source ./emsdk_env.sh
emsdk install latest-fastcomp
emsdk activate latest-fastcomp

Use the following commands to compile:

cd third_party/liblouis/src
cp ../cvox-common.cti tables/
./autogen.sh
emconfigure ./configure --disable-shared
emmake make
emcc ./liblouis/.libs/liblouis.a -s RESERVED_FUNCTION_POINTERS=1 -s MODULARIZE=1 \
