• Switch CSV geometry parsing from GeoJSON to WKT format
• WKT is the default output format of osm2ch, simplifying setup

**BREAKING CHANGE:
Existing CSV files with GeoJSON geometry will no longer work.

• To make it work it is recommended to reconvert is via osm2ch
• or here is snippet in python if you don't want to run osm2ch again:

# convert_to_wkt.py
import json, sys, re

def convert(match):
    g = json.loads(match.group().replace('""', '"').strip('"'))
    if g['type'] == 'Point':
        return f"POINT({g['coordinates'][0]} {g['coordinates'][1]})"
    else:  # LineString
        coords = ', '.join(f"{c[0]} {c[1]}" for c in g['coordinates'])
        return f"LINESTRING({coords})"

for filename in sys.argv[1:]:
    with open(filename) as f:
        content = f.read()
    result = re.sub(r'"?\{""type""[^}]+\}"?', convert, content)
    with open(filename, 'w') as f:
        f.write(result)
    print(f"Converted: {filename}")
