Improve console output formatting.

[ADmad]

The current console error/info output feels messy and not very readable (even with code snippets turned off) if you have largish number of errors.

It would be nice if it was possible to get a compact output with errors groups by file like phpstan or somewhat tabular display like phpcs.

If you provide a format you'd like I could implement it as an option in --output-format

What both of them have in common is that they output errors grouped by file (psalm outputs ungrouped list), as well as highlighting the file name (psalm doesn't highlight it). However default psalm output includes snippets, which is also quite useful, so one line per issue is not achievable unless snippets are dropped. But grouping could be done.

If you're looking into the output format, it would also be nice to support terminal hyperlinks

I would like to have an out which resembles the following:

FILE: /path/to/code/myfile.php
--------------------------------------------------------------------------------
SEVERITY | LINE | ISSUE                   | DESCRIPTION
--------------------------------------------------------------------------------
ERROR    |    2 | InvalidArgument         | Lorem ipsum
INFO     |  120 | NullableReturnStatement | Lorem ipsum
--------------------------------------------------------------------------------

Columns 1 and 2 column be swapped to keep it similar to phpcs.
