spruce-release Release v1.29.0

New Features

• Adds a new (( negate <bool> )) operator to flip a boolean, in order
  to help DRY up yaml configs needing boolean inversions.

• (( stringify )) now supports literals, to allow for things like `(( stringify this_optional_key || "default message" ))

• Bumps to golang 1.17.1, and updates dependencies

Fixes

• Addresses an issue in the (( static_ip )) operator that could result in
  integer overload or wraparound if compiled on an architecture where golang's
  default size of an int was not int64.
