Twf crashes, if the passed path is not a child of the current working directory.

Hello,

thanks for this nice tool. I'm currently trying to use it to replace NERDtree etc. in vim. Unfortunately, twf crashes, when the path passed to it is not a child of the current working directory. This also happens with plain twf without vim:

• twf build from master on Arch Linux.
• Reproduction steps without vim:

  cd /tmp
  twf /home

• Error:

  
  panic: Path not found: /home

goroutine 1 [running]: main.main() github.com/wvanlint/twf/cmd/twf/main.go:69 +0x7d0

I find this especially important for the vim use case:

cd /tmp vim /home/foo

in vim, trying to navigate the directory of the opened buffer

! twf /tmp

Results in an error:

panic: Path not found: /home

goroutine 1 [running]: main.main() github.com/wvanlint/twf/cmd/twf/main.go:69 +0x7d0

shell returned 2

Press ENTER or type command to continue

late but... twf -dir /any/other/dir [optional/file/to/focus]

Notes from the README:

It is also possible to locate and highlight a file given as an argument. twf path/to/subdir/file

-dir <dir>: Root directory to browse.
