chore: Update Go to 1.19

feat: Add DeleteKeysByPattern method

• chore: Update Go to 1.18
• fix: Delete empty go.sum
• fix: Increment miss cache stats before unlocking the mutex

• Removed persistence features #6
• Removed server features #6

As of now, this library is strictly an in-memory cache and has 0 dependencies.

This is a breaking change, therefore the version is going from v1.x to v2.x

⚠ Migrated TwinProduction/gocache to TwiN/gocache

Minor fixes

• Restructured server packages
• Improved documentation

Replaced bolt by bbolt for persistence

Added Cache.GetValue

• Added Cache.WithForceNilInterfaceOnNilPointer

In Go, an interface is only nil if both its type and value are nil, which means that a nil pointer
(e.g. (*Struct)(nil)) retains its type when passed as an interface{}, and the unmodified value returned from
Cache.Get, for instance, would return false when compared with nil.

This new configuration allows a cache to bypass that counter-intuitive behavior by setting the value to nil if a nil pointer is passed as the value parameter to a write function (Set, SetWithTTL and SetAll), which effectively sets both the type and the value of the cache entry to nil, thus allowing the statement value == nil to be true.

The default value for that new configuration is true, because this behavior is more intuitive.

• (BREAKING) Cache.Stats() no longer returns a pointer
• Fixed race conditions

Fixed issue with Cache.Stats().ExpiredKeys not incrementing on active deletion of expired keys

• GetKeysByPattern no longer returns expired keys
• Fixed issue caused by calling StopJanitor when the janitor wasn't started

• (BREAKING) Renamed GetAll to GetByKeys and add GetAll function
• Significantly improved test coverage
• Improved documentation

I don't make it a habit of making breaking changes, especially without increasing the major version in the tag, but since there are very few people using this library, I'll make an exception.

gocache

• Added stats on cache hits and cache misses
• Switched to Bolt for persistence to reduce peak memory usage on save #3
• RelevantTimestamp is now updated when an existing entry is modified

gocacheserver

• Added logs during auto saves
• Added used_memory, used_memory_human, used_memory_dataset and used_memory_dataset_human to INFO output

The switch to Bolt is a breaking change, but since this library isn't used by many at the moment - much less the persistence feature - not updating the major version should be acceptable.

gocache

• Implemented eviction based on maximum memory usage #2 #4
• Fields of the Cache struct are now exposed through functions rather than being directly accessible

gocacheserver

• Implemented eviction based on maximum memory usage #2 #4

The last change of the gocache section is a breaking change, but considering the meager popularity of the repository at the moment, not updating the major version should be acceptable.
