+/**
+ * This function handles a new type of key-import format
+ * For example, a key can be imported as such:
+ * {
+ *   pub: "xpub20412049182341234"
+ *   xlmpub: "GSLKJASDFJASLFASDFAS"
+ *   signature: "IK/alkjELASJFLAKJSDFLAKSFASDFW=="
+ *   xlmSignature: "KOPASIK------PSDIFAPSDFOAF"
+ *   path: "100"
+ * }
+ * If this key comes in, we can save it either as type xpub or xlm (depending on what the admin specifies on the command line)
+ * If the above key is imported as type 'xlm', we will change it to the following format:
+ * {
+ *   pub: "GSLKJASDFJASLFASDFAS"
+ *   signature: "KOPASIK------PSDIFAPSDFOAF"
+ *   path: "100"
+ * }
+ * Notice that we replaced the pub and signature fields with the XLM info.
+ * Alternatively, if the key is specified to be an xpub, we would just remove the XLM info and continue as normal
