Warn when no config files found

[charliefoxtwo]

It would be very helpful if we could warn log when no config files are located, perhaps including the directory being searched in the log message.

DCS-BIOS-Communicator/DcsBiosCommunicator/Configuration/AircraftBiosConfiguration.cs

Lines 32 to 55 in 1ae0126

	public static async Task<AircraftBiosConfiguration[]> AllConfigurations(string? aliasesFileName = null, ILogger<AircraftBiosConfiguration>? logger = null,
	params string[] configLocations)
	{
	var allFiles = configLocations.SelectMany(GetAllJsonFilesBelowDirectory).ToList();
	var aliasTasks = allFiles.Where(f => f.Name == aliasesFileName).Select(f => GetAliases(f, logger));
	var aliasResults = await Task.WhenAll(aliasTasks);
	var aliases = new Dictionary<string, HashSet<string>>();
	foreach (var result in aliasResults)
	{
	foreach (var (key, value) in result)
	{
	aliases.Add(key, value);
	}
	}
	var configTasks = configLocations
	.SelectMany(GetAllJsonFilesBelowDirectory)
	.Where(f => f.Name != aliasesFileName)
	.Select(f => BuildFromConfiguration(f, aliases, logger));
	return (await Task.WhenAll(configTasks)).Where(c => c != null).Select(c => c!).ToArray();
	}
