Fix Enum.slice deprecation warning in parse_udp

[bruschke]

Summary

• Fixes Elixir 1.18 deprecation warning in parse_udp/2
• Replaces deprecated Enum.slice(0..-2//-1) with Enum.slice(0..-2//1)

Issue

When connecting to SQL Server instances via UDP for instance discovery, users see this warning in Elixir 1.18:

warning: negative steps are not supported in Enum.slice/2, pass 0..-2//1 instead
  (elixir 1.18.4) lib/enum.ex:3015: Enum.slice/2
  (tds 2.3.5) lib/tds/protocol.ex:394: Tds.Protocol.parse_udp/2

Changes

• Updated line 394 in lib/tds/protocol.ex to use the correct range syntax
• The behavior remains identical (slicing all elements except the last one)
• No functional changes, only syntax update for Elixir 1.18 compatibility

Test plan

• Existing tests should pass
• The warning will no longer appear when connecting to SQL Server instances
