Read stream and other types as buffer*

constread=require('as-buffer');conststream=fs.createReadStream('./photo.png');read(stream,{maxsize: 1e6})// with a max-size, default to 1e7, 10MiB.then(buf=>console.log('read',buf)).catch(e=>console.log('file too large'));

*: exception of object-mode streams that are returned as array
