Client-side caching for fonts and tiles #72

RD-235

Objective

Add client-side caching using browser Cache API to reduce network load for repeated sessions.

Description

transformRequest + addProtocol used to hook into the maplibre
The cache is reused even between different map sessions (mtsid and key are ignored).
Soft limit of 1000 items in the cache, checked periodically, oldest items are then removed.
Special handling for TileJSON to actually propagate Last-Modified to the tile requests (so that the cache is not reused when outdated).

Acceptance

Tested locally
