pass a URL with jimp.read and have option to pass "rejectUnauthorized : false" to the request

Expected Behavior

I would like to pass an option rejectUnauthorized : false to the Jimp.read()` method when I pass a URL to it. I want to read the image even if there is a problem with the certificate. I don’t want to configure the behaviour globally to the server.

Current Behavior

If I have somehow troubles to get the certificate of the URL, I get the following error => Error: unable to verify the first certificate

Failure Information (for bugs)

Error unable to verify the first certificate _tls_wrap.js in TLSSocket.<anonymous> at line 1105:38 events.js in emitNone at line 106:13 events.js in TLSSocket.emit at line 208:7 _tls_wrap.js in TLSSocket._finishInit at line 639:8 _tls_wrap.js in TLSWrap.ssl.onhandshakedone at line 469:38

Steps to Reproduce

Jimp.read(‘https://404store.com/2017/12/08/Random-random-30798866-500-325.jpg’)

Context

• Jimp Version: 0.4.0
• Operating System: Unbuntu Server 16.04
• Node version: v8.11.1
