[#188] transformer: Allow to provide size hint For big objects with known size we can optimize allocation patterns by providing size hint. As with any hint, it does not affect transformer functionality: slices with capacity > MaxSize are never allocated. ``` goos: linux goarch: amd64 pkg: git.frostfs.info/TrueCloudLab/frostfs-sdk-go/object/transformer cpu: 11th Gen Intel(R) Core(TM) i5-1135G7 @ 2.40GHz │ out │ │ sec/op │ Transformer/small/no_size_hint-8 65.44µ ± 3% Transformer/small/no_size_hint,_with_buffer-8 64.24µ ± 5% Transformer/small/with_size_hint,_with_buffer-8 58.70µ ± 5% Transformer/big/no_size_hint-8 367.8m ± 3% Transformer/big/no_size_hint,_with_buffer-8 562.7m ± 0% Transformer/big/with_size_hint,_with_buffer-8 385.6m ± 7% geomean 5.197m │ out │ │ B/op │ Transformer/small/no_size_hint-8 13.40Ki ± 0% Transformer/small/no_size_hint,_with_buffer-8 13.40Ki ± 0% Transformer/small/with_size_hint,_with_buffer-8 13.39Ki ± 0% Transformer/big/no_size_hint-8 288.0Mi ± 0% Transformer/big/no_size_hint,_with_buffer-8 1.390Gi ± 0% Transformer/big/with_size_hint,_with_buffer-8 288.0Mi ± 0% geomean 2.533Mi │ out │ │ allocs/op │ Transformer/small/no_size_hint-8 92.00 ± 0% Transformer/small/no_size_hint,_with_buffer-8 92.00 ± 0% Transformer/small/with_size_hint,_with_buffer-8 92.00 ± 0% Transformer/big/no_size_hint-8 546.5 ± 0% Transformer/big/no_size_hint,_with_buffer-8 607.5 ± 0% Transformer/big/with_size_hint,_with_buffer-8 545.5 ± 0% geomean 228.1 ``` Signed-off-by: Evgenii Stratonikov <e.stratonikov@yadro.com>
