lmdb-js database files format

[partok]

Does lmdb-js use some special LMDB format for the db files?

• I get a segmentation fault when opening a LMDB database created in C (with LMDB 0.9.32)
• I can't open a LMDB database created with lmdb-js using lmdbnav (https://github.com/PowerDNS/lmdbnav) "Error: mdb_env_open: MDB_INVALID: File is not an LMDB file"

(lmdb-js installed with "npm i lmdb")
