`prettyPrintFileSystemType()` returns incorrect spelling for LittleFS

[aliphys]

When the prettyPrintFileSystemType() method is applied to a LittleFS partition, it correctly identifies it as a LittleFS partition. However, the spelling is LitlleFS when it should be LittleFS instead.

Partition: 1
Size: 12284
Type: LitlleFS

This is repeatable, by running the following AUA_SPIS_FORMAT_002.ino test sketch:

Sketch

``` #include "Arduino_UnifiedStorage.h" #include // Create a vector of partitions with one partition of 16MB using LittleFS std::vector partitioningScheme = { {12288, FS_LITTLEFS}, // 12 MB LittleFS Partition }; const char testCaseID[] = "AUS_SPIS_FORMAT_002"; void setup() { Serial.begin(115200); while (!Serial); Serial.println("---"); Serial.print("Test Case ID: "); Serial.println(testCaseID); Serial.println("---"); Arduino_UnifiedStorage::debuggingModeEnabled = true; if (Arduino_UnifiedStorage::debuggingModeEnabled) { Serial.println("Arduino_UnifiedStorage debug messages ON."); } bool partitioned = InternalStorage::partition(partitioningScheme); // list all partitions std::vector partitions = InternalStorage::readPartitions(); for (int i = 0; i < partitions.size(); i++) { Serial.println("Partition: " + String(i + 1)); Serial.println("Size: " + String(partitions[i].size)); Serial.println("Type: " + prettyPrintFileSystemType(partitions[i].fileSystemType)); Serial.println(); } } void loop() { } ```
