windyboy 53f03bbc0a refactor: Update config.dev.toml and sub.go for Hasura integration
The code changes in config.dev.toml and sub.go update the configuration and message handling for integrating with Hasura. The config.dev.toml file now includes a new section for Hasura configuration, specifying the endpoint and secret. In sub.go, the UUID field is set to the UUID of the received message, ensuring proper tracking of parsed messages. This refactor enables seamless integration with Hasura and improves the functionality of the code.

// fplPatternString is a regular expression designed to parse and extract detailed information from formatted flight plan strings.

//
// - category: Matches a three-letter flight category code.
// - number: Matches the flight number, consisting of letters followed by digits.
// - indicator: Matches a two-letter indicator.
// - aircraft: Matches the aircraft registration or type, which may include a slash and an optional letter.
// - surve: Matches surveillance equipment information, capturing any characters in this segment.
// - departure: Matches the four-letter code of the departure airport.
// - departure_time: Matches the four-digit departure time.
// - speed: Matches the speed, consisting of letters followed by digits.
// - level: Matches the flight level, which can include letters and digits.
// - route: Matches the flight route, capturing any characters in this segment.
// - destination: Matches the four-letter code of the destination airport.
// - estt: Matches the four-digit estimated time of arrival.
// - alter: Matches the four-letter code of an alternate airport.
// - pbn: Matches performance-based navigation equipment information.
// - nav: Matches navigation equipment information.
// - reg: Matches the aircraft registration.
// - eet: Matches the estimated elapsed time, including the four-letter code and four-digit time.
// - sel: Matches the SELCAL code.
// - performance: Matches a single letter indicating the aircraft's performance category.
// - rif: Matches reroute information, including any characters in this segment.
// - remark: Matches remarks, capturing any characters in this segment.
//
// The regular expression uses named capture groups for each segment, allowing for easy extraction of specific information from a matched flight plan string.
