Performance

Basic Searching methods are inherited from node-ip2region, the data source is replaced with Indonesia only

Four searching methods are implemented, including BinarySearch and BtreeSearch based on both file search and memory search

The default searching method is inMemoryBtreeSearch

Test result is as follows：

$ node test/benchmark.js

search x 742,123 ops/sec ±0.78% (86 runs sampled)
inMemoryBinarySearch x 168,323 ops/sec ±1.05% (89 runs sampled)
inMemoryBtreeSearch x 163,726 ops/sec ±2.11% (81 runs sampled)
binarySearchSync x 15,210 ops/sec ±1.00% (87 runs sampled)
btreeSearchSync x 63,495 ops/sec ±1.80% (76 runs sampled)
Fastest is search
