Nested Fields create an empty object if the parent field doesn't exist

Hello,

With the config above a new document will always have field1: {} if field1 is not provided.

const subUserSchema = new Schema({
  field2: {
    type: String,
  },
});

const userSchema = new Schema({
  field1: {
    type: subUserSchema,
  },
});

userSchema.plugin(encrypt, { encryptionKey: encKey, signingKey: sigKey, encryptedFields: ["field1.field2"], });

IMHO, field1 should not be created, WDYT?

Version "mongoose-encryption": "1.5.0",

I definitely agree. I wonder if this relates to #65

I don't have time to dig into this in the near-term, but would be happy to review any PRs accompanied with tests!

Why not for the PR.

But before, by reading the Encrypt Specific Fields of Sub Docs section in the README.md file, i resolved the problem.

const subUserSchema = new Schema({
  field2: {
    type: String,
  },
});

subUserSchema.plugin(encrypt, { encryptionKey: encKey, signingKey: sigKey, encryptedFields: ["field2"], });

const userSchema = new Schema({
  field1: {
    type: subUserSchema,
  },
});

Maybe Nested Fields section should be replaced by Encrypt Specific Fields of Sub Docs section in the README file.

I don't see any differences between nested fields & sub docs, WDYT ?

Ah that makes sense. Apparently there is a difference at the Mongoose level (though Mongo itself of course doesn't really care), hence the support for both.
