wip: route-pattern trie + benchmarks

[pcattori]

• parsing a flat AST designed for generation of variants and trie branches
• generate variants from AST
• generate RegExp from AST
• bench AST parsing
• create full RoutePattern from a set of ASTs (one for each part like protocol, hostname, pathname, etc.)
• create segment-based trie from AST variants
• trie returns resolved params
• Feature: ranking
• Matcher.match
• Matcher.matchAll
• Feature: .join
• Feature: port matching
• Feature: matching on search constraints
