Workaround for static libs for swift/objc projects

[theangelperalta]

Description

This PR implements a workaround to allow the generation of static library using cocoapods.

Use case 1:

target 'App' do
  use_modular_headers!
  pod 'mamba', '2.2.0'
end

Use case 2 (without global a use_frameworks!):

target 'App' do
  pod 'mamba', '2.2.0'
end

Change Notes

• Added new import macro to RapidParserError.m.
