ascii's Issues

Possible to use buffer as input?

I want to render an ASCII representation of an image stored as a nodejs buffer. Will this library work for this purpose? How would I bypass the file read operation and pass a buffer in directly?

Making it work with external URL ?

Heyo

Awesome project, love it! it works as expected!
Just a question tho, what if I want to make it work with external files ?
Like, giving it an url as url parameter.

This would be rad.

Thanks!

my code
`
let attachment = message.attachments.first().url;
const options = {
url: attachment,
dest: 'image' // Save to /path/to/dest/image.jpg
}
download.image(options)
.then(({ filename, image }) => {
let pic = new Ascii(image/filename);
pic.convert(function(err, result) {
message.channel.send(result);
})
}).catch((err) => {
message.channel.send("Error occured, please retry.");
console.log(err);
});

Using the code in the readme.md file, it writes the error.

`
var pic = new Ascii('https://i.imgur.com/rNd3mIH.png');
