support destructuring modules

[aspeddro]

Currently the following code is parsed as a call_expression. Actually this is destructuring modules https://rescript-lang.org/docs/manual/latest/module#destructuring-modules

let {baz, _} = module(User.Inner)

Before:

(source_file [0, 0] - [1, 0]
  (let_binding [0, 0] - [0, 33]
    (record_pattern [0, 4] - [0, 12]
      (value_identifier [0, 5] - [0, 8])
      (value_identifier [0, 10] - [0, 11]))
    (call_expression [0, 15] - [0, 33]
      function: (value_identifier [0, 15] - [0, 21])
      arguments: (arguments [0, 21] - [0, 33]
        (variant [0, 22] - [0, 32]
          (nested_variant_identifier [0, 22] - [0, 32]
            (module_identifier [0, 22] - [0, 26])
            (variant_identifier [0, 27] - [0, 32])))))))

After:

let_binding [0, 0] - [0, 33]
  record_pattern [0, 4] - [0, 12]
    value_identifier [0, 5] - [0, 8]
    value_identifier [0, 10] - [0, 11]
  module_destructuring_expression [0, 15] - [0, 33]
    module_identifier_path [0, 22] - [0, 32]
      module_identifier [0, 22] - [0, 26]
      module_identifier [0, 27] - [0, 32]

Great, thank you!
