Fix missing custom headers on core api charge

[rizdaprasetya]

Issue

midtrans-python-client/midtransclient/core_api.py

Lines 39 to 43 in 49cb73c

	response_dict, response_object = self.http_client.request(
	'post',
	self.api_config.server_key,
	api_url,
	parameters)

Specific for CoreApi’s charge func is missing to implement params:

     self.api_config.custom_headers,
     self.api_config.proxies

For example, the expected full params:

midtrans-python-client/midtransclient/core_api.py

Lines 58 to 64 in 49cb73c

	response_dict, response_object = self.http_client.request(
	'post',
	self.api_config.server_key,
	api_url,
	parameters,
	self.api_config.custom_headers,
	self.api_config.proxies)

Impact:

• causing self.api_config.custom_headers to be unexpectedly ignored (not used).
