new: dev: parse_argument accept engines parameter
new: dev: split search query from get_result func
new: test: basic result case
Suggestions: use RawTextQuery to make the suggestions URLs. Update all themes accordingly.

* new: doc: searx import and init

* chg: dev: parse_argument

- doc
- run on __main__
- simple parse_args

* chg: doc: module

* chg: dev: import section

- remove unused python path modification
- new required package

* chg: dev: script run

- parse_argument func return directly parsed results
- main func return dict instead json text
- dump directly on sys.stdout.write

* chg: dev: get_search_query and get_search_query func

* chg: dev: main func

- move inner function outside
- return dict instead of json text

* new: dev: add utils to doc sys path

* new: doc: standalone_searx

* fix: doc: run script

* chg: dev: mypy type hint

* chg: dev: SearchQuery don't have attr engines

* chg: dev: reset engines __init__

* chg: test: unit test update

* chg: dev: pylint and flake8

* new: test: standalone_searx

* chg: dev: main func and doc

* chg: dev: import and type hint

* new: dev: main func

- remove get_result func
- single func which just translate dict

* chg: test: put mypy on dev requirement

"""Script to run searx from terminal.
Getting categories without initiate the engine will only return `['general']`
>>> import searx.engines
... list(searx.engines.categories.keys())
['general']
>>> import searx
... searx.engines.initialize_engines(searx.settings['engines'])
... list(searx.engines.categories.keys())
['general', 'it', 'science', 'images', 'news', 'videos', 'music', 'files', 'social media', 'map']
Example to use this script:
.. code:: bash
$ SEARX_DEBUG=1 python3 utils/standalone_searx.py rain
Example to run it from python:
>>> import importlib
... import json
... import sys
... import searx
... import searx.engines
... search_query = 'rain'
... # initialize engines
... searx.engines.initialize_engines(searx.settings['engines'])

... engine_cs = list(searx.engines.categories.keys())
... # load module
... spec = importlib.util.spec_from_file_location(
... 'utils.standalone_searx', 'utils/standalone_searx.py')
... sas = importlib.util.module_from_spec(spec)
... spec.loader.exec_module(sas)
... # use function from module
