Add swift format ignore & disable swift lint for generated file

[mikelikespie]

I noticed our swift format really wants to reformat these files. It would be nice to make the codegen include

// swift-format-ignore-file
// swiftlint:disable all

at the beginning of each file, similar to what swift-protobuf codegen library does. This would prevent them from being auto-formatted.

@mikelikespie Good suggestion - especially since there's already a precedent set in the generated code from swift-protobuf.

@mikelikespie This is implemented in v1.0.4, which is now available.
