fromFilePairs can't take list of paths

Bug report

Expected behavior and actual behavior

We'd like to be able to specify a list of specific URLs for use with fromFilePairs as follows, however it doesn't yet seem to be possible.

Steps to reproduce the problem

ch_read_files = Channel.fromFilePairs([
  'https://github.com/nf-core/test-datasets/raw/methylseq/testdata/SRR389222_sub1.fastq.gz',
  'https://github.com/nf-core/test-datasets/raw/methylseq/testdata/SRR389222_sub2.fastq.gz',
  'https://github.com/nf-core/test-datasets/raw/methylseq/testdata/SRR389222_sub3.fastq.gz'
], size: 1)

Program output

Invalid method `call` invocation with arguments: /nf-core/test-datasets/raw/methylseq/testdata/SRR389222_sub1.fastq.gz (nextflow.file.http.XPath) on _fromFilePairs0_closure10 type

Environment

• Nextflow version: 19.11.0-edge build 5173
• Java version: java version "1.8.0_144"
• Operating system: macOS

Is it available in an edge version already?

Nope, only avail on master. I'll make an edge release in a couple of weeks.
