Create simpleProcessStringTelex() to easily try libbogo.js out

To test, build libbogo.js with:

$ emmake make clean libbogo.html

Then open libbogo.html and open Javascript console in your browser.
Run the following commands, each on its own line:

js > process = Module.cwrap('simpleProcessStringTelex', 'string'['string'])
js > process('meof')
mèo

To get execution time, use console.time():

js > console.time('my test'); console.log(process('meof')); console.timeEnd('my test');
my test: 1.29ms
