v6.1.0

Added

• Bitwise stdlib
• Set stdlib
• Option.force_msg
• Loading namespaces into the current scope (e.g. using Pair)
• Assign patterns to variables (e.g. let x::(t = y::_) = [1, 2, 3, 4] where t == [2, 3, 4])
• Add builtin types (AENS.name, AENS.pointee, Chain.ttl, Chain.base_tx, Chain.ga_meta_tx, Chain.paying_for_tx) to
  the calldata and result decoder
• Patterns guards

  switch(x)
    a::[] | a > 10 => 1
    _              => 2
  

  function
    f(a::[]) | a > 10 = 1
    f(_)              = 2
  

Changed

• Fixed the ACI renderer, it shouldn't drop the stateful modifier
