refactor: modularize GPX types into separate modules
Split monolithic types.ml into focused modules for better organization:
- coordinate.ml - GPS coordinate types and validation
- error.ml - GPX error types and handling
- extension.ml - GPX extension support
- gpx_doc.ml - Main GPX document structure
- link.ml - Link/URL types
- metadata.ml - GPX metadata types
- route.ml - Route and route point types
- track.ml - Track and track point types
- waypoint.ml - Waypoint types
Updated all dependent modules to use new modular structure.

(** {1 MLGpx - OCaml GPX Library}
2
-
3
-
A high-quality OCaml library for parsing and generating GPX (GPS Exchange Format) files.
4
-
GPX is a standardized XML format for exchanging GPS data between applications and devices.
5
-
6
-
{2 Overview}
7
-
8
-
The GPX format defines a standard way to describe waypoints, routes, and tracks.
9
-
This library provides a complete implementation of GPX 1.1 with strong type safety
10
-
and memory-efficient streaming processing.
11
-
12
-
{b Key Features:}
13
-
- ✅ Complete GPX 1.1 support with all standard elements
14
-
- ✅ Type-safe coordinate validation (WGS84 datum)
15
-
- ✅ Memory-efficient streaming parser and writer
16
-
- ✅ Comprehensive validation with detailed error reporting
17
-
- ✅ Extension support for custom elements
18
-
- ✅ Cross-platform (core has no Unix dependencies)
