🚀 v3 Request: Merge `static` and `filesystem` middleware as `static` middleware

[efectn]

Feature Description

I think we should merge static and filesystem to make Fiber core simple in v3. Also there's no performance problem when we compare fasthttp.FS static and io/fs filesystem middleware. (https://github.com/gofiber/fiber/pull/2027)

How to deal with embed.FS after merging?

How to deal with embed.FS after merging?

embed.FS is compatible with fs.FS (io/fs) interfaces. So it can be used without extra effort. So it'll be easier to use fs interfaces with https://github.com/gofiber/fiber/pull/2027

Fasthttp FS is not well with fs interfaces but it may be improved in the future. https://github.com/valyala/fasthttp/pull/1374 Perhaps we can remove filesystem middleware in v3 cuz of there will no pros over fasthttp FS after this improvement.

Got it. Thank you @efectn .

embed.FS is compatible with fs.FS (io/fs) interfaces. So it can be used without extra effort. So it'll be easier to use fs interfaces with #2027

Fasthttp FS is not well with fs interfaces but it may be improved in the future. valyala/fasthttp#1374 Perhaps we can remove filesystem middleware in v3 cuz of there will no pros over fasthttp FS after this improvement.

how to suppport Compress option? use app.Static method, you can set Compress option.

app.Static("/", "web", fiber.Static{
	Compress:  true,     // <---- HERE
	ByteRange: true,
})

Probably we will remove filesystem middleware after fasthttp FS gets fs.FS support. (For v3) https://github.com/valyala/fasthttp/pull/1374

Don't have much knowledge about PR at the moment. Not reviewed yet

The implementation of this patch is far off！

Update, fs.FS support seems to be in fasthttp now. valyala/fasthttp#1640
