Missing config object in sample files

[RobinMaas95]

Hey,
in both sample files no config object is passed to TemplateMiner. This should cause TemplateMiner to fall back to the default .ini file. However, if you use the call from the readme python -m examples.drain_stdin_demo to call the examples, there is no drain3.ini in the current working directory ("main" directory) and thus no config file is used. This leads to the fact that the examples cannot be reproduced, since no masking templates are used.

I think the cleanest way would be to create config objects in the examples.
Output of the current version:

python -m examples.drain_stdin_demo
Starting Drain3 template miner
Loading configuration from drain3.ini
config file not found: drain3.ini
Checking for saved state
Saved state not found
Drain3 started with 'FILE' persistence, reading from std-in (input 'q' to finish)
IP is 12.12.12.12
Saving state of 1 clusters with 1 messages, 352 bytes, reason: cluster_created (1)
{"change_type": "cluster_created", "cluster_id": 1, "cluster_size": 1, "template_mined": "IP is 12.12.12.12", "cluster_count": 1}

Proposed fix (e.g. drain_stdin_demo.py Line 45):

config = TemplateMinerConfig()
if os.path.exists(os.path.join("examples","drain3.ini")):
    config.load(os.path.join("examples","drain3.ini"))
else:
    logger.error("Drain3.ini file not found")

template_miner = TemplateMiner(persistence, config)

Fixed Output:

python -m examples.drain_stdin_demo
Starting Drain3 template miner
Checking for saved state
Saved state not found
Drain3 started with 'FILE' persistence, reading from std-in (input 'q' to finish)
IP is 12.12.12.12
Saving state of 1 clusters with 1 messages, 940 bytes, reason: cluster_created (1)
{"change_type": "cluster_created", "cluster_id": 1, "cluster_size": 1, "template_mined": "IP is <IP>", "cluster_count": 1}

Thanks for the report and the fix. Did a little different fix eventually but it should work now.
