GeoStyler SLD Parser

The `geostyler-sld-parser` package provides an implementation of a GeoStyler style parser for Styled Layer Descriptor (SLD) XML. It facilitates the conversion between the GeoStyler's internal, technology-agnostic style object model and OGC SLD XML documents. The current stable version is 8.4.2, with releases occurring frequently, often on a monthly or bi-monthly basis, indicating active development and maintenance. Its key differentiator is its role within the broader GeoStyler ecosystem, enabling seamless interoperability and transformation of styling information across various geospatial platforms and formats, using a unified API. This parser handles both reading SLD XML into a GeoStyler style object and writing a GeoStyler style object out to SLD XML, including complex features like filters, symbolizers, and vendor options.
