v0.5.3 — application-defined TLV range (0xE0..=0xEF)

What's new

Adds an ExtensionTlv::Custom { type_id: u8, value: Vec<u8> } variant that carries arbitrary opaque payloads in the application-defined PROXY protocol v2 range (0xE0..=0xEF, per HAProxy v2 spec § 2.2). Consumers can now ride extra connection metadata through a v2 header without forking the crate.

• Encoder emits the stored type_id byte + raw payload.
• Parser accepts any type_id in 0xE0..=0xEF and surfaces it as Custom { type_id, value }. Unknown type_ids outside both the builtin types and the application range still error — the parser doesn't become a catch-all.
• Two new public constants on ExtensionTlv: CUSTOM_TYPE_MIN = 0xE0, CUSTOM_TYPE_MAX = 0xEF.

Compatibility

ExtensionTlv is already #[non_exhaustive], so adding a variant is a non-breaking change for downstream pattern-match call sites (existing code keeps compiling). No wire-format change for any builtin TLV — Custom is purely additive.
