Proxy Support & TLS Validation (PR#6)

• Added support for making requests through a proxy.

• Introduced a parameter to explicitly disable TLS validation when needed.

  >>> proxy_dict = {
  ...     "http": "http://192.168.1.243:9080",
  ...     "https": "http://192.168.1.243:9080"
  ... }
  >>> from ultra_rest_client import RestApiClient

• TLS validation warnings are now suppressed by default.

• Updated README.md with details on proxy usage and TLS validation options.

Resign Zone Method (PR#8)

• Added a method to resign DNSSEC-signed zones in the client wrapper.

Support for RD Pools (PR#7)

• Added a method for creating RD pools.

  Example Usage:

  # Demonstration of creating an A record RD pool
  client.create_rd_pool(
      "example.com", # Zone name
      "foo", # Hostname (owner)
      300, # TTL
      [
          "1.1.1.1", # List of rdata 
          "2.2.2.2", 
          "3.3.3.3"
      ]
  )
  
  # Demonstration of creating an AAAA pool
  client.create_rd_pool(
      "example.com", 
      "bar", 
      300, 
      [
          "2001:db8::1",
          "2001:db8::2", 
          "2001:db8::3"
      ], 
      ipv6=True, # Set AAAA to True
      order="RANDOM", # (Optional) Order of record distribution
      description="lorem ipsum" # (Optional) Description of pool
  )

• Added a method for replacing existing RD pools (PUT).

  Example Usage:

  client.edit_rd_pool(
      "example.com", 
      "bar", 
      600, 
      [
          "2001:db8::2", 
          "2001:db8::3"
      ], 
      ipv6=True, 
      order="FIXED", 
      description="ipsum"
  )

• Added a method for retrieving all RD pools.

  Example Usage:

  client.get_rd_pools("example.com")

• Added a delete method for removing an RD pool.

  Example Usage:

  client.delete_rd_pool("example.com", "foo")
  client.delete_rd_pool("example.com", "bar", ipv6=True)

• Updated README.md with RD pool example.
