Node v12.14.1
let captcha = svgCaptcha('TEST2', {size: 5}) should return a captcha with the text TEST2, but returns undefined instead.
Alternatively I tried let captcha = svgCaptcha.create('TEST2', {size: 5}), but it didn't work ether.
Thus I propose that the create function has a text option also which produces the result of seeing TEST2 as captcha text when that text is given to the create function.
