Add OR logic filters for multiple values of same type

[Copilot]

Enables filtering on multiple values of the same filter type using OR logic. Previously, users could only specify a single value per filter type (except peer_ips).

Changes

New filter variants with OR semantics:

• origin_asns - comma-separated origin ASNs
• prefixes, prefixes_super, prefixes_sub, prefixes_super_sub - comma-separated prefixes with match types
• peer_asns - comma-separated peer ASNs

Implementation:

• Added Filter::OriginAsns(Vec<u32>), Filter::Prefixes(Vec<IpNet>, PrefixMatchType), Filter::PeerAsns(Vec<u32>) variants
• Extracted parsing helpers parse_asn_list(), parse_prefix_list(), parse_ip_list() to handle comma-separated values
• Validation: skips empty strings from consecutive/trailing commas, requires at least one value
• Matching uses .any() for OR logic within each filter
• Updated peer_ips to use same validation pattern
• All new filters support negation with ! prefix

Usage:

// Match elements from ANY of the specified origin ASNs
let parser = BgpkitParser::new(url)
    .add_filter("origin_asns", "13335,15169,8075")
    .unwrap();

// Match elements with ANY of the specified prefixes
let parser = BgpkitParser::new(url)
    .add_filter("prefixes", "1.1.1.0/24,8.8.8.0/24")
    .unwrap();

// Combine filter types (AND between types, OR within)
let parser = BgpkitParser::new(url)
    .add_filter("origin_asns", "13335,15169")  // OR
    .add_filter("type", "a")                    // AND
    .unwrap();

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

Please enable filter to be filtering on multiple filters with the same type with OR logic. For example, if specified multiple prefixes, the filters should return ANY match of the prefixes. The same should goes to origin ASNs or any other types that applies.
