[akiver]

This PR mimic the following Source 1 game events with CS2 demos based on prop updates:

• WeaponFire
• RoundStart
• RoundEnd
• RoundEndOfficially
• BombPickup
• BombDropped
• BombPlantBegin
• BombPlantAborted
• BombPlanted
• BombDefuse
• BombExplode
• BombDefuseStart
• BombDefuseAborted
• FlashExplode

Test code:

package main

	demoinfocs "github.com/markus-wa/demoinfocs-golang/v3/pkg/demoinfocs"

	defer p.Close()

	_, err = p.ParseHeader()
	checkError(err)

	p.RegisterEventHandler(func(e events.RoundStart) {

	})

	p.RegisterEventHandler(func(e events.BombDefuseAborted) {

}

Hey, great job here! If I may have a suggestion, we should probably add something like MimicSource1Events (and maybe set to true in the DefaultParserConfig) to the parser config to make it explicit that we do not actually have these events in the Source 2 demos.

amazing work - great job!

@akiver can you change MimicSource1Events to DisableMimicSource1Events?

That way it will be enabled by default for users using custom configs, not just those using the DefaultParserConfig.
