Proposal: Replace yaml with toml

[mpdevilleres]

as of python 3.11 toml parser is part of standard library.

what does it mean for the project is as follow.

• remove third party dependency (PyYAML)
• improve readability of configuration reference

current yaml

#########################
# main settings

domain: yourdomain.com
ns1: 127.0.0.1
ns2: 127.0.0.1

#########################
# other configurables

# server address
listen_addr: 0.0.0.0:53

# debug (0 or 1)
debug: 0

# default TTL
ttl: 60

# default latency (in ms)
sleep: 0

# a 3rdparty domain which we don't own
a3rdparty_domain: whatever.com

# known DNS resolvers / clients connecting to us
known_servers:
  127.0.0.1:      localhost
  1.2.3.4:        powerdns1
  1.2.3.5:        powerdns2
  2.3.4.5:        bind-test1
  4.5.6.7:        msdns-test1

#########################

will look like with toml

[main]
domain = 'yourdomain.com'
ns1 = '127.0.0.1'
ns2 = '127.0.0.1'

# server address
listen_addr = '0.0.0.0:53'

# debug (0 or 1)
debug = 0

# default TTL
ttl = 60

# default latency (in ms)
sleep = 0

# a 3rdparty domain which we don't own
a3rdparty_domain = 'whatever.com'

known_servers = """
127.0.0.1   localhost
1.2.3.4     powerdns1
1.2.3.5     powerdns2
2.3.4.5     bind-test1
4.5.6.7     msdns-test1
"""

just a little caveat this will not work to python 3.10 below. so it will be a good idea to update the readme stating this only works with python 3.11 and above.
