Preserve comments and newlines

[ReyOrtiz]

Hello and thanks for creating this, very helpful!

Is it possible to preserve all the comments and new lines generated by buf?

For example, this part:

# -*- coding: utf-8 -*-
# Generated by the protocol buffer compiler.  DO NOT EDIT!
# NO CHECKED-IN PROTOBUF GENCODE
# source: project/protos/abc.proto
# Protobuf Python Version: 5.28.2
"""Generated protocol buffer code."""
from google.protobuf import descriptor as _descriptor
from google.protobuf import descriptor_pool as _descriptor_pool
from google.protobuf import runtime_version as _runtime_version
from google.protobuf import symbol_database as _symbol_database
from google.protobuf.internal import builder as _builder
_runtime_version.ValidateProtobufRuntimeVersion(
    _runtime_version.Domain.PUBLIC,
    5,
    28,
    2,
    '',
    'project/protos/abc.proto'
)
# @@protoc_insertion_point(imports)

_sym_db = _symbol_database.Default()


from validate import validate_pb2 as validate_dot_validate__pb2
from google.protobuf import struct_pb2 as google_dot_protobuf_dot_struct__pb2

is rewritten as

"""Generated protocol buffer code."""
from google.protobuf import descriptor as _descriptor
from google.protobuf import descriptor_pool as _descriptor_pool
from google.protobuf import runtime_version as _runtime_version
from google.protobuf import symbol_database as _symbol_database
from google.protobuf.internal import builder as _builder
_runtime_version.ValidateProtobufRuntimeVersion(_runtime_version.Domain.PUBLIC, 5, 28, 2, '', 'project/protos/abc.proto')
_sym_db = _symbol_database.Default()
from ...validate import validate_pb2 as validate_dot_validate__pb2
from google.protobuf import struct_pb2 as google_dot_protobuf_dot_struct__pb2

It removed all the # comments and removed the new lines.
