replace whoosh with tinydb

[sbrunato]

Check how TinyDB could replace whoosh in eodag. Usage example:

import re
from eodag import EODataAccessGateway
from tinydb import TinyDB, Query
from tinydb.storages import MemoryStorage


dag = EODataAccessGateway()
pts = dag.list_product_types()

db = TinyDB(storage=MemoryStorage)
db.insert_multiple(pts)

ProductType = Query()

filtered_s2 = db.search(ProductType.ID.matches(r'S2_*'))
filtered_keywords = db.search(ProductType.keywords.matches(r'.*sentinel.*', flags=re.IGNORECASE))
