FIX - CRS compound CRS showed invalid URL and added max cache size

[Bang Pham Huu]

Compound CRS in SECORE returns incorrect value for EPSG:3035

URL: https://crs.rasdaman.com/def/crs-compound?1=https://www.opengis.net/def/crs/OGC/0/AnsiDate?axis-label=%22time%22&2=https://www.opengis.net/def/crs/EPSG/0/3035

</CompoundCRS>

reason is https://www.opengis.net/def/crs/EPSG/0/3035 has

<gml:identifier codeSpace="EPSG">3035</gml:identifier>

while https://crs.rasdaman.com/def/crs/EPSG/0/3035 has

> <gml:identifier codeSpace="IOGP">https://www.opengis.net/def/crs/EPSG/0/3035</gml:identifier>

then SECORE CrsCompoundHandler parsed the former CRS to show only 3035 instead of the full URL in the latter.

Also, added new setting in secore.properties called max_cache_size to control how much data SECORE should cache.
