Improvements and Changes

• run_and_measure now only measures the qubits that are used in a program
  (rather than all qubits on the device) when the target QAM is a QVM without
  noise. This prevents the QVM from exhausting memory when it tries to allocate
  for e.g. 32 qubits when only e.g. 2 qubits are used in the program (@notmgsk,
  #1252)

• Include a py.typed so that libraries that depend on pyquil can validate
  their typing against it (@notmgsk, #1256)

• Fix Apache 2 license (@mpharrigan, #1255)

• Removed warnings expected in normal workflows that cannot be avoided
  programmatically. This included the warning about passing native Quil to
  native_quil_to_executable. Documentation has been updated to clarify
  expected behavior (@mhodson-rigetti, gh-1267).

Bugfixes

• Fixed incorrect return type hint for the exponential_map function, which
  now accepts both float and MemoryReference types for exponentiation
  (@mhodson-rigetti, gh-1243).
