The logger library using the experimental Golang slog package

Usage:

• The package was designed to be a simple interface over the slog package extracing out some if the discoverability features and crafting a simple, easy logger.
• creating a new logger with NewLogger function. The input is an io.Writer, so stdout or a file work (any any io.Writer implementation)
• All variadic values passed to the LogEvent/LogError functions will be treated as key value pairs, any additional values, that are not mapped to their preceeding values, are added as "misc" fields to the JSON return.

Example Usage:

• create a logger with slogger.NewLogger(os.Stdout)
• or log to a file:

f, _ := os.OpenFile(testFile, os.O_RDWR|os.O_TRUNC, os.ModeAppend)
log := slogger.NewLogger(f)
stdoutLogger.LogEvent("info", "Send data to file") 

• slogger will accept any number of arbitrary elements and create a json structure from the arguments to the LogEvent functions.
• i.e.

stdoutLogger.LogEvent("info", "Something", "one", "two", "Another", false, "four", true)

output:

stdoutLogger.LogEvent("info", "Something four", "one", "two", "Another", false, "four", true)

• You can also pass a map to the LogEvent functions as unput:

stdoutLogger.LogEvent("info", "Something four", map[string]any{"one": false})

output:

{"time":"2022-12-27T19:19:22.711393515-08:00","level":"INFO","msg":"Something four","one":false}

• You can even pass a combination of map strings:

stdoutLogger.LogEvent("warn", "aaaa", "key", "value", "AnotherKey", false, "four", 123123, map[string]any{"testOne": 42069, "testTwo": false})

output:

stdoutLogger.LogEvent("warn", "aaaa", "key", "value", "AnotherKey", false, "four", 123123, map[string]any{"testOne": 42069, "testTwo": false})

• Example of Misc fields:

{"time":"2022-12-27T18:56:27.543409183-08:00","level":"INFO","msg":"Something four","one":"two","Another":false,"four":true,"miscFields":"bob"}

Output:

• Example test output:

{"time":"2022-12-27T18:56:27.543409183-08:00","level":"INFO","msg":"Something four","one":"two","Another":false,"four":true,"miscFields":"bob"}
{"time":"2022-12-27T18:56:27.543564927-08:00","level":"INFO","msg":"Something four","one":"two","Another":false,"four":true}
{"time":"2022-12-27T18:56:27.543572397-08:00","level":"INFO","msg":"Something four","one":false,"Another":false,"four":true}
{"time":"2022-12-27T18:56:27.543577644-08:00","level":"INFO","msg":"A thing","key":"value","AnotherKey":false,"four":123123,"more":"","MORETEST":123123,"TestAgain":false,"miscFields":123123}
{"time":"2022-12-27T18:56:27.543583676-08:00","level":"WARN","msg":"aaaa","AnotherKey":false,"four":123123,"testOne":42069,"testTwo":false,"key":"value"}
{"time":"2022-12-27T18:56:27.543587977-08:00","level":"ERROR","msg":"error","err":"something died"}
{"time":"2022-12-27T18:56:27.54359305-08:00","level":"ERROR","msg":"error","1":2,"3":"masdasd","err":"something died"}
