xpanic
panic 辅助函数
error不为nil时，panictrue时，panictry cache panic
例子
Do(func() {
fmt.Println("Doing something...")
panic("Something wrong happened!")
}, func(p *Panic) {
fmt.Println("Caught a panic:", p.Reason)
})
AutoRecover("something", func(){
// do something
// if panic, auto execute this function continue.
})
Try(func() {
WhenErrorAsFmtFirst(err, "%w, %d", 1)
}).Catch(func(err E) {
fmt.Println(err)
})
Output:
error, 1
# Functions
AutoRecover 执行 f ，当 f 发生panic，启动新的协程重复 AutoRecover.
go:generate optiongen --option_with_struct_name=true --option_return_previous=false.
Catch recovers from panic.
Do executes f.
InstallAutoRecoverOptionsWatchDog the installed func will called when NewAutoRecoverOptions called.
NewAutoRecoverOptions new AutoRecoverOptions.

WhenError err 不为 nil 则 panic.
WhenErrorAsFmtFirst err 不为 nil 则 wrap 并 panic，将 err 作为第一个 fmt 的参数 xpanic.WhenErrorAsFmtFirst(err, "got error: %w while reading file: %s", filePath).
WhenFalse 当 condition 为 false 时 panic.
WhenHereNotNil 提供运行到此处返回的error应为nil的语义，避免在框架层吃掉error 功能逻辑等同WhenError，但是语义上调用者确定这里不会返回错误.
WhenTrue 当 condition 为 true 时 panic.
WithAutoRecoverOptionDelayTime 每次panic后重启delay的时间 Note: 这里应该可以直接对接到retry package，复用重试逻辑.
WithAutoRecoverOptionOnRecover 如果指定了该函数，recover panic的时候，会执行该函数，默认输出error日志.
# Structs
AutoRecoverOptions should use NewAutoRecoverOptions to initialize it.
Panic is a snapshot of a panic, containing both the panic's reason and the system stack.
