request_options not passed to Square::Internal::JSON::Request in Square::Inventory::Client

[davidmtmdesign]

As an example, passing additional_headers doesn't work for Square::Inventory::Client because request_options is not passed to Square::Internal::JSON::Request#new. So it's not possible to set the Square-Version header.

Example of problematic code:

_request = Square::Internal::JSON::Request.new(
  base_url: request_options[:base_url] || Square::Environment::PRODUCTION,
  method: "GET",
  path: "v2/inventory/#{params[:catalog_object_id]}",
  query: _query
)

Probably should be something like this:

_request = Square::Internal::JSON::Request.new(
  base_url: request_options[:base_url] || Square::Environment::PRODUCTION,
  method: "GET",
  path: "v2/inventory/#{params[:catalog_object_id]}",
  query: _query,
  request_options: request_options
)

This is how it's done in Square::Catalog::Client.
