cmd: add hashSUM file support (#5352) 
Currently rclone check supports matching two file trees by sizes and hashes.
This change adds support for SUM files produced by GNU utilities like sha1sum.

Fixes #1005 

Note: checksum by default checks, hashsum by default prints sums.
New flag is named "--checkfile" but carries hash name.
Summary of introduced command forms:

```
rclone check sums.sha1 remote:path --checkfile sha1
rclone checksum sha1 sums.sha1 remote:path             
rclone hashsum sha1 remote:path --checkfile sums.sha1
rclone sha1sum remote:path --checkfile sums.sha1
rclone md5sum remote:path --checkfile sums.md5
```

rclone hashsum

Produces a hashsum file for all the objects in the path.

Synopsis

Produces a hash file for all the objects in the path using the hash named. The output is in the same format as the standard md5sum/sha1sum tool.

By default, the hash is requested from the remote. If the hash is not supported by the remote, no hash will be returned. With the download flag, the file will be downloaded from the remote and hashed locally enabling any hash for any remote.

Run without a hash to see the list of all supported hashes, e.g.

$ rclone hashsum
Supported hashes are:
  * md5
  * sha1
  * whirlpool
  * crc32
  * dropbox
  * mailru
  * quickxor

Then

$ rclone hashsum MD5 remote:path

Note that hash names are case insensitive.

rclone hashsum <hash> remote:path [flags]

Options

      --base64               Output base64 encoded hashsum
  -C, --checkfile string     Validate hashes against a given SUM file instead of printing them
      --download             Download the file and hash it locally; if this flag is not specified, the hash is requested from the remote
  -h, --help                 help for hashsum
      --output-file string   Output hashsums to a file rather than the terminal

See the global flags page for global options not listed here.
