Implement a non-Core FFLogs plugin to check parses

[MKhayle]

Describe the solution you'd like
(Also from #3, thanks @ArcaneDisgea, expanded that a bit much for more depth so that we may discuss it)

This non-Core FFLogs plugin should cover basic transactions with FFLogs' API to display data tied to a character.
It may involve a per-server configuration so that specialized Discord servers can choose which default duties are to be displayed by the bot, with additionals query parameters to choose specific duties. Some other plugins may want to depend on it for the API integration. In addition, it should handle commands to display various datas / statistics on specific duties, character parses, and maybe curate some job data (highest percentiles damage value on content, parse counts for a specific job, etc).

• FFLogs API integration
• Embeddable stats to display data from FFLogs
• Per-server configuration for default duties
• Maybe some feature to get a XIVAnalysis link out of a given / the most recent log on a specific duty ?

Potential user commands examples
/fflog Player Character@Server (P1S) (BLM) > displays a brief summary of the character's best current tier parses or on a specific duty or on a specific job
/toplogs Player Character@Server P1S > displays the top 5 parses of a character on a specific duty
/analysis Player Character@Server P1S > displays XIVAnalysis links of the most recent logs on a specific duty for a specific character
