Possibility of corruption of store data on app termination

[ghost]

Hello, I've been using this lib for some time now in my project. However, I found that my stores and data get corrupt at times. Upon examination, I found that data might be corrupted if the app is killed during the converter.write call, resulting in an incomplete write and so a corrupt file. This seems like a critical issue with this lib, IMHO could be solved by writing the data to a randomly named temporary file and then doing a rename-overrite to the key name so that at no point in time the store file is in an invalid state.

Totally agree! I'll jump on this next chance I get 😄
