v0.3.0

This is a major update in how the Toolshed source code gets compiled. If you are
calling any Toolshed functions in your programs, you may need to update the
calls. All enabled functions get compiled to be in the Toolshed module now.

• Backwards-incompatible updates

  • Removed file path completion. This was improved and added to Elixir 1.13.0
    in December, 2021.
  • Moved all helper functions to Toolshed. They are no longer accessible in
    other modules. This should go unnoticed if you're using Toolshed at the IEx
    prompt.

• Improvements

  • ping - Changed ping command to use Erlang's relatively new support for
    sending ICMP echo requests. Previously ping made TCP connection requests.
    The old way is now available via the tcping helper. Thanks to @amclain for
    the ICMP update.
  • ping - ping and tcping repeat 3 times by default instead of repeating
    forever. The new :count option can be used to repeat more.
  • inspect_bits - Added inspect_bits helper to easily print a number in
    multiple bases. It also handles negative numbers and gives hex and binary
    representations that are more familiar to those coming from languages with
    fixed size integers.
  • (Nerves-only) poweroff -Added helper to gracefully power off Nerves
    devices that support it.
  • httpget - Increased the timeout for downloads and added :timeout option
    to change it at runtime.
  • Nerves helpers are completely compiled out when not using Nerves. This can
    be extended to remove or selectively enable helpers in the future.

Thanks to @mnishiguchi for making Toolshed significantly easier to maintain by
improving the code organization and adding tests.
